Titanium studio setup issue (multiple xcode/ios)

I was not able to build sample test app with iOS Simulator. Also I see only iphone is enabled and ipad is not. I have multiple xcode (4.0, 4.0.1, 3.2.5 and 3.2.1) installed on machine.

When I create a new app and build, it actually build to ios 3.1.3 as defa开发者_StackOverflow社区ult. Here is my log http://pastebin.com/y9uX1RSz It finds all sdk and it quits the simulator as soon as it open.

There is an option to change the android sdk folder, but there is no alternative to change the ios SDK version in preferences.

I even try to modify the build deployment sdk to 4.2 with no luck. Also I see there are some plist (stylesheet.plist and debugger.plist) missing. And no demos (kitchensink) available as part of mobilesdk.

I've downloaded Titanium studio 1.0.1 which downloads mobilesdk 1.7.1 on its initial run. It is the same with mobilesdk 1.7.2 which I've downloaded separately and copied to /library/Application support/Titanium

Update:

The issue is, I was not able to run a sample prj with iphone simulator. Ironically it works if I try to build with Android. The same mobile sdk works if I try from Titanium developer 1.2.2, but I was not able to develop or run sample code with Titanium studio.
