phonegap with xcode 4 won't run on ios 3.1.3 (UIKIT)

When running a simple HelloWorld phonegap project , on iPhone 4 with 4.3.2 OS it works great

But when I tried to run it on iPhone 3 with 3.1.3 OS I have came across with a problem 开发者_运维知识库with the CoreMedia lib which i needed to 'weak' in the build settings.

Once I worked this one out, I came across with a whole new problem which I couldn't find a solution for:

dyld: Symbol not found: _UIAccessbilityAnnouncmentNotifcation .... Excpeted in /SystemLibrary/Frameworks/UIKit.framework/UIKIT

Both Project and Target Deployment Target is 3.1

Any idea's? Thanks in advance Guy.

sorry for necromancing, i'm just answering if you still have this problem or someone else encounters it. The following solution may help:

This is covered in the README FAQ. Basically you need to weak link three frameworks for iOS 3.x:
1. CoreMedia
2. AVFoundation
3. UIKit

Try that and see if that solves your problem.
