My application requires multi touch, so I was checking the documentation and could't find the property to require multi touch. Do all versions of iOS devices support multi touch or I am missing something?
Thanks in advance
There is no need to configure that. Every iOS device in existence (including the first-gen iPhone) supports multi-touch (unless its screen is defective). A pinch gesture, for example, is considered a multi-touch gesture, and is found in built-in apps like Maps and Mobile Safari.

I want the assistive touch to automatically slide to Left side of my iPhone when open my application and the app detects that assistive touch is not on the Left side.
So any way to acheive this?
Thanks.
I think you cannot control the assistive touch because Apple has not provided any official APIs for that. I tried googling about it, But I didn't found any relevant link regarding controlling the Assistive Touch.
I am developing an app for iPhone.
I am looking for a way to run some code once a drag gesture is recognized on the homescreen (or on all screens if possible).
Does anyone know how to get this with the iOS SDK using Xcode and Objective-C?
Your app cannot receive gestures anywhere in iOS except within itself and its own views while it's active (not counting system notifications and the app icon).
I doubt this is possible. To do this, you will need to hook into the OS at a lower level than is usually allowed.
iOS is locked down much more than Mac OS, I'm afraid.
iPhone 4 has a mic on bottom-left, iPhone 3GS and earlier had a mic on bottom-right.
How can I detect where is the mic on iPhone? What function does that?
You will have to detect the specific model of device (e.g. "iPhone2,1", etc.) and do a table look-up from information you determine. And to future-proof the result, you may also have to have it look up the position of the mic from your web site, where you can keep a table updated with device types as Apple introduces new ones.
I would not use the method as said in the comment to your post. The minute the new iPad or iPod Touch is released with a front facing camera, your application is off.
Why not just use a method like in this post: Determine device (iPhone, iPod Touch) with iPhone SDK
The code (if you scroll a bit down) shows how to detect which version of iPod/iPhone/etc is running on.
How to disable the multitouch capabilities in new iPhone application?
Multi-touch tracking is not enabled by default, so in effect you need not do anything. See "multipleTouchEnabled" in the documentation for UIView.
I need to record a video of a multitouch game I'm working on, and I'd like to record it from the simulator. My idea was to send touches from the device to the simulator (like this project does with the accelerometer). Just by googling I haven't found anything like that, but before I start implementing it I thought I'd ask here if anyone knows about an already existing solution.
Just to be clear, I do need full multitouch (up to 5 fingers). The pinch and drag that are available on the simulator are not enough.
Matt Gallagher has a writeup on synthesizing touch events, which might provide what you're looking for, although I've not tested it myself.
Check out iSimulate, it is an application/library pair that allows you to use to multi-touch (up to 5 fingers), the accelerometer, and the GPS in the iPhone Simulator. It takes only few minutes to integrate into your iPhone project.
