What is the best way to store data for the iPhone? I will be developing an iPhone app in Objective-C which will take data from end users. This data will need to be save and loaded at various points.
Essentially, what is the best combination of languages and frameworks to use in order to develop the above (i.e. should I be aware of any compatibility or like issues regarding the objective-c language)?
EDIT: Are there any particular reasons why to choose sqllite over core data?
Hey, the best way to store and manage data is Core Data framework, you can read about it in official docs.
Two of the most popular and reasonable solutions:
Apple's native solution: CoreData
sqlite3
I used sqlite3 for my applications. If you use mySQL then you'll be very comfortable to use sqlite3. However, people recommend CoreData due to its ease of use and iOS support.
I would also like to add my vote for the CoreData solution. I investigated all the options (CoreData, sqlite3 and plists) and CoreData seemed to be the right option for me.
I found a brilliant tutorial on it for iOS 5 here

I have an Android app I wrote that uses a sqllite database, now I am writing the same app for iPhone. How do I use the existing sqllite database from my android app in the iPhone version?
More specific questions:
Where do I place the actual sqllite database - What folder?
Can I just use iPhone sql statements to open and read the data?
Could I just use an xcode emulator until I move the iPhone app to an actual device?
If you're happy with using sql, you don't necessarily need to go through the CoreData pain barrier. Ray Wenderlich also has a good tutorial on using Sqlite directly in your app here:
Part 1 - SQLite 101 for iPhone Developers (Intro)
Part 2 - SQLite 101 for iPhone Developers (The actual coding with Sqlite)
His site is a great resource for experienced developers wanting a quick and practical guide to getting started with almost every aspect of iOS development imaginable.
Here you can find a tutorial about how to import a SQLite Databse to core data:

I have a SQLite database that I want my app to read and load into a UITableView then push to a Detail View.
I am using the FMDB wrapper framework (https://github.com/ccgus/fmdb). I'm confused as to how exactly to do this as I've never used SQLite in an iPhone app before.
Can anyone help get me started? What code do I need to add to I'm assuming viewDidLoad?
I think you should use CoreData framework provided in iPhone SDK. Its pretty simple to use and it manages most of the complex things for us. It provides a way to use Sqlite database as a persistent store for your application. You can just start with it from the documentation provided in iPhone SDK documentation under "Core Data Programming guide" section.
I'm writing a simple iOS App to manage Email address, maybe like Contacts. I don't know what is the best way to organize data in iOS and don't know which database that iOS and Xcode support. I just know that iOS supports XML & SQLite, are there other databases supported?
Which is the best database (XML, SQLite,...) for this app?
If you are going to add only email and contacts then my suggestion is you just use plist.

You should try CoreData. Have a look here to see what's it about. It offers a great way to handle the things you said you want to achieve.
CoreData is good option. The persistence used by core data is abstracted away while you can still choose SQLite, XML, or in memory for the persistent store.
I am planning to develop an iPhone application heavily relying on sqlite DB ,
from different links I have gone through this seems to be a great tool and has some really good support.
As my app is still in the planning process
I would like to ask if there are any Issues with SQLlite database ? from memory management to Queries and data sizes and multiple access etc;
Please share your experience using SQLite DB in iPhone and what problems did you face?
I just want to make a note of these exceptions so that I may plan my App well and do not have any issues raised in the middle of the development process.
Thanx for your contribution.
If you are not looking to support the OS version 2.x or below I would (as the apple and may be the other developers) suggest to use the core-data. Its a lot simpler and easy to handle than sqlite. See the apple support and this sample for more help.
Thanks,

Can anyone tell me the best way to go about making an iPhone application support multiple languages? I am going to put separate versions for each language in the App Store, but what is the best way to represent this in Xcode?
Putting a separate app in the store for each language is NOT the way to go. The iPhone SDK handles multiple languages with grace, and you only need to have a single app with all the various translations. The iPhone's locale setting will direct your app as to which language to use.
A good place to start is here.
I haven't done iPhone dev yet, but "normal" Cocoa apps use ".lproj" strings files for different languages. See the docs about those, that should help. Good luck.
