UI less application in iOS4 - iphone

I'm new to mac/iOS development. I'm thinking of to develop a UI less application by using existing Apps/Libraries.
I want to know whether following things will be possible to make or not, it will be great if someone provides me some insight.
Here are my questions:
Is it possible to show/hook additional buttons on existing contacts
-> contacts view (some additional buttons under FaceTime button)?
Is it possible to route some messages to SMS inbox? where the user
feels like he received/sent the real SMS?

In short: no.
In somewhat longer: iOS applications run in a sandbox that rather severely limits their ability to interact with the outside world. This is for the purpose of protecting the user's security and experience using the device. It MIGHT be possible to accomplish both of those things if you were running on a jailbroken device and using non-public APIS (though frankly I doubt you'd be able to add buttons to the existing contacts list by any means at all). But such an app couldn't be sold in Apple's app store.

iOS give users default downloadable content

I'm facing this problem while designing my iOS app. Suppose that a user purchases an app and downloads it to the iPhone. I would like to provide him with a default consumable item the first time he runs the app to use whenever he wants , however I would also like to track if the user has already consumed the item. This way if he decides to reinstall the app we can restore the transactions (if he used the item) or we can avoid possible intents to download different kind of content by reinstalling app and consuming default items each time. (Guess NSUserDefaults is not an option here).
One approach that came to my mind was using UDID(or any iOS 6 alternatives) to keep a record on server of the user's device the moment he uses the default item. But this will limit items just to the device from which they consumed content.
It would be great to support all the user's devices (like inAppPurchases), but I can't figure out a way to implement this.
Any suggestions or help would be great.
Thanks a lot.
In order to tie information to a user (not just a device she used at one time), you'll need to ask the user to identify herself and save it someplace other than the device. In other words, a backend that implements registration and login.
From scratch, this can be a lot of effort that an iOS developer didn't count on. Fortunately, there are several services in the world that provide a substantial head start. Here's a nice round-up. I've had direct experience only with Parse.com, and think it's excellent.

Monitoring the other Apps from one app in iPhone

I need to create and App that will run in the background and will monitor the user's behavior in term of applications installed, opened and deleted.
i.e Application will save the information in the database that at what time user has installed/opened/deleted an application in iphone.
I wonder if its possible and Apple will allow this??
I tried to google on it but did not get anything, i know if its possible then it would be possible by multiasking only??
Can any one please help me on the same.

Not possible. Your app can only run when the user chooses to (except for a limited sub-set of tasks like VoIP, etc).
Your app can know nothing about other apps.
iOS apps are sandboxed. I wouldn't say impossible but certainly not allowed. You'd have to find a security hole to give you root access first. Oh, and notify us when you do ;).
Edit:
Maybe it wasn't clear in my post but I was at least half joking. Not sure why you want to do what you want to do. I can imagine the following scenarios:
1) Your company wants to monitor everything their users do on their phones. In that case I would either
a) lock them down and only allow app installation through a company portal (enterprise distribution is possible in iOS) OR
b) forget about iOS alltogether. Blackberry would probably be closer to what you want, although I don't really have experience with that platform. Also, its future is not sure.
2) You're trying to do something illegitimate. Because of iOS's locked down nature it won't be easy. See how few successful attacks there have been in the last years - and that's for a highly successful platform where an attack could be high paying both in terms of money and reputation.

Can a native ipad app written in HTML5+Javascript+CSS accomplish the same things as one written in objective C

I would like to build an iphone/ipad app that has social networking capabilities and the ability to sell magazines and specific articles. I would also like this app to be able to be as flexible as possible for future features.
Should I insist the developer use objective C or could he accomplish the same thing with HTML5 etc..
If you're the client, and have specific technical requirements, you should document them from a technical POV. If not, well that's why you're hiring a developer--for their expertise.
There's pros and cons to each and we'd need to have a lot more project details to be of any specific help for you.
Do note that selling items via an app has its own set of red tape political issues with Apple. You may want to tackle that aspect of the project first. If you don't want to route any payments through Apple so they can take their cut, then you might want to rethink the app model and consider a mobile web site avenue instead.
UPDATE:
In general, here's some high-level comparisons:
Native Apps:
Pros
can access native device functionality directly
can leverage the native UI more directly
can be much more performant in situations like heavy game animation, 3-d, image/video editing, ec.
may be smaller file sizes
Cons
have to be written per-device
different devices use different native IDEs and Languages
HTML5/Phonegap apps
can be written with cross-platform Web standards
can still leverage native device features to an extent
are easier to port from device to device (though still takes effort)
Cons
you won't be creating graphic-heavy game-type apps with it now
may be a bit slower than a native app
Pure HTML5 local web app
This is different than something like a phonegap solution. PhoneGap takes HTML5 and compiles it into native code. That means you can send it through the app store. There's another option, however, where you put the HTML5 app on your web server, and then a user requests to keep it locally on their device. The advantage is that this allows you to bypass the app store completely (though in most situations, people prefer to go through the app store)
I would say, "no", you shouldn't insist the developer use Objective-C. At least not unless other requirements not mentioned dictate the need for a native app. As DA mentioned, there are App Store policies that would need to be complied with for native apps that can be avoided by creating a web app. Also, if you choose, it would be easier to produce a web app that could be used across other platforms rather than being restricted to the iPad.

Phone development: interact with the call?

Today, the focus of a cell phone's capabilities is drifting away from plain making a phone call.
And somehow, this shows in the API's too. Therefor I'm wondering: if I want to write an app that e.g. pitches up, records, scrambles... an incoming call - you know, the voice on the other side -, what aspect of the API should I use?
I looked into Android, into Windows Phone, iPhone... (briefly), but had no luck. Is this just unintended usage?
This is also not possible with Windows Phone 7. There were, however, API methods for interacting with incoming and outgoing calls and texts in Windows Mobile.
The reason this is not possible in Windows Phone 7 comes down to a deliberate decision around data security and the aim that apps on the phone shouldn't be able to do something without the user specifically knowing about it. This prevents, amongst other things, malicious apps having information about or access to potentially sensitive data.
This is not possible in Android, except maybe via firmware modifications.
There’s no way to do that with the iPhone SDK. It may be possible through jailbreaking, but I’m not familiar enough with it to speak on it.
Given the limited accessibility of in-call audio but ready access to microphone/speaker and data on current smartphones, would probably be easiest to do this as part of a VOIP calling application.

What is the iPhone SDK Missing?

I've been doing mobile app development for a long time (2001?), but the systems we worked with back then were dedicated mobile development environments (Symbian, J2ME, BREW). iPhone SDK is a curious hybrid of Mac OS X and Apple's take on mobile (Cocoa Touch).
But it is missing some stuff that other mobile systems have, IMO. Specifically:
Application background processing
SMS/MMS application routing (send an SMS to my application in the background)
API for accessing phone functions/call history/call interception
I realize that Apple has perfectly valid reasons for releasing the SDK the way they did. I am curious what people on SO think the SDK is missing and how would they go about fixing/adding it, were they an Engineering Product Manager at Apple.
The biggest shortcoming in my opinion is support for separating licensing from distribution.
What I mean by this is that it should be possible to download a trial version of an application and later purchase a license for that application (from an API call inside the application or from the app store). This would make it much easier to try-before-you-buy and get rid of the current duplicates of many applications with 'lite' versions.
I think lack of push notifications for apps is the big thing we're missing right now. With push, you can register your application to perform a task (like getting the most recent data from a web service) even when it's not running, at a time and frequency the OS decides is best. In an ideal world, along with the existing concept of iPhone apps loading quickly and resuming where you last left off, this solves the problem of not running in the background. I know some tasks will be more difficult or maybe impossible with this strategy, but it's still a pretty good compromise between third party applications and the iPhone's limited hardware.
Originally push was scheduled for last September, but it was removed from the beta SDK and not spoken of since then.
API's I'm personally looking for:
Apple80211 as a public API (private, current API is fine if documented)
Access to Volume buttons (semi-accessible via Celestial, private, needs new API)
Access to Calendar (private, API status unknown)
Access to Bluetooth + SPP profile (status unknown)
Access to Camera (directly, API status unknown)
Access to JavaScript runtime (directly, not through UIWebView, API status unknown)
WebKit access that's lower-level than UIWebView (private, current API is fine)
Access to Music Library (private, current API is fine)
Garbage Collection.
CoreData is missing.
You've mentioned some of the big ones - copy & paste (or in fact any way for apps to collaborate) is another huge omission.
It also seems to lack a desktop synch framework (at least if it exists I can't find it).
Language independence and especially lack of scripting is another pet peeve - objective-c is all very well but more languages to choose from would be good.
Inability to dynamically extend apps, via scripts or otherwise, is another big omission. This is partly an SDK/OS issue, partly licensing.
My list ordered by priority:
Mapping abstraction (the MapKit looks awesome), but that would require a new Google Maps TOS
Music library
Camera (photo + video) Access to more
UIViews, Apple designed some pretty nice custom ones for their apps
Better UIWebKit abstraction
The features I see missing that it should have is
Access to SMS
Direct Access to Google Maps App. You should be able have access to this so you could extend your application to use the built in features provided by Google Maps.
Access to the Bluetooth functionality of the phone.
Access to the Calendar. Why not allow access to simply post a calendar event for the user.
Access to Active Sync. It would great if we could directly access this and communicate back to the Exchange Server.
Core Image. They provide Core Animation but Core Image is missing. I hope that this is added to the API soon.
These are some of the features that my clients have access for in the past and are supprised when they are not available.
We definitely miss a Calendar API and SMS access. So many applications could leverage such APIs. The iPhone allows users to have everything in their pocket, but it's almost useless as long as developers cannot leverage this integration in their apps.
A language with proper namespaces.
A limitation that bugs me is lack of access to system features that require root or setuid. For example: opening privileged IP ports.
I'm not sure there is a good solution to this, as long as Apple's policy is to keep the device locked-down.
Allow program to set some kind of local timed event for your application to bring up an alert and launch your app if the user agrees (like any calendar app). You could do that with push notifications but there are many cases I'd hate to have to rely on a whole server infrastructure and network connectivity just to basically do some timed thing.
Some idea of what direction the user is facing. I cannot believe the GPS chip the newer iPhones use are not capable of reporting direction.
I would personally love to see
Access to the CoreTelephony Framework (Currently private). Which allows access to all the phone functions (Especially sending MMS / SMS).
Some sort of ability to run stuff in the background. While push notifications is ok for most things, but it is a bit hard to leverage CoreLocation (i.e. have the app show a notification at a certain location). Of course this would probably need an on/off button or app specific like push is.
animation view which will be reduce developer to make a cool app , of course the core business local still need consider more , but the view layer could more easy to use ....
