upgrading iPhone OS from 3.1.2 to 3.2 or 4.x

[Amit Dewan]

I have iPhone with OS version 3.1.2
I am developing iphone App in xcode 3.2.3 on Mac OS X
when I transfer my app from xcode to device it says your device has lower version and cant build your app.
xcode 3.2.3 has support for ios version 3.2 and 4.x only.
Please tell me how can I put my app on device.
Can I upgrade my iPhone device OS to 3.2 or 4.x ?
or is there any other possibility in xcode to build for ios 3.1 ? or can i download and install previous version of xcode.
Please help

There are two configurations for OS version. One is for what you are compiling your app with. and one for which versions your app supports.

So for compile, "xcode 3.2.3 has support for ios version 3.2 and 4.x only. " that is your choices. This has absolutely nothing to do with what your app supports and can be installed on.

For instance, my TubeOrganizer app runs on phones with 3.1 or higher, but it was compiled with the 4.1 SDK

You can update any iPhone device. Just connect the device to your computer start up iTunes. You will only get the latest OS to upgrade to, you cannot upgrade to older OS versions that the most current.

But, in your scenario, why do you want to upgrade? You do not have to upgrade in order to get your app to compile and run on your current device. It supports all the way back to version 2.x in XCode 3.2.3. You just have to change your project settings.
