Do any of the Android tablets (such as the Motorola Xoom with Honeycomb) or the iPad 2 support detection of 10 or more finger multi-touch? I need that capability for an app idea.

iPad(1) does 11 fingers, i heard iPad2 does 10, prolly 11 aswell.

Android honeycomb also supports 10 fingers:
"Like the iPad, the Xoom will also have 10-finger touch capabilities"

Edit: if you need even more fingers, you will have to develop for win7, 3m made a screen that officially supports 30 fingers, but the below article talks about detecting a whopping 50 points!

but yea, thats just a stretch

Are new iPhone apps still required to support the old iPhone 3GS and other non-retina devices? I'm wondering because I already have a full set of retina graphics and I want to submit the app without having to create a set of non-retina graphics.
This is a matter of personal preference. Apple Inc. says that you must support the retina display but there is nothing that prevents you from supporting the lower versions of the iPhone. If you want to reach those who still use older iDevices, you can. But there are not many left out there. It is up to you, though. I believe you have a wide audience using devices that use retina display, but using a lower target deployment is not a bad idea for increasing the sales of your application.
iOS 7 isn't going to run on a 3GS, so if you want to run on iOS 7 only, then you don't have to worry about it.

I have a quick question, related to if these images of apps, uses UICollectionView or buttons in their design:
Thank you for the help.
Most likely buttons, as UICollectionView is only compatible with iOS 6+
The LinkedIn iOS app only requires iOS 4.3+ so it is not using a UICollectionView-- they most likely built a custom view using UIButtons
Most apps out there still want to support at least iOS 5+ so your not going to see many using the UICollectionView yet.
Here are some open source "Collection View" classes that may fit your need (just make sure they also support old iOS versions)

I found this post that suggests to use AirServer to capture video from iPhone. Unfortunately AirServer doesn't support iPods (even though I have a 4th gen iPod running iOS 5.0). Is there a way via software or should I get my iPod to connect to a TV and record it there? I have seen that there are some good cables to connect iPod to TV but I lost the link and now can find only suggestion that explains how to do it on jailbroken iPods.. (which I don't want to do).
EDIT (For the one that closed the topic): is there any code snippet that I can use to send the video data from my app to AirServer?

How can we support printer in a iPhone application? I want to print a page from my application. Do I need to code for this in my app or this is a default operation supported by IOS. I am using IOS 4.3 & above.
Look at the Drawing and Printing Guide for iOS.
iOS can only print to "AirPrint" printers of which there aren't many. There are some apps that run on OS X that will "AirPrint enable" any attached printer. I use Printopia (no affiliation other than as a happy user). There are some free ones but I haven't had as much success with them.
It's always a good idea to google your question first :)
