Debugging on iOS 4.0.1 Device crashing

Trying to fix a bug on iOS 4 but when I debug it crashes with these errors: SDK is installed in seperate directory as I need to deug 3.1.3 as well

Developer_Xcode3_2_3_iOS_SDK_4_0_1

Device is running 4.0.1

Any ideas? Cheers

Someone asked had I created symlinks A few months ago when 3.0.1 came out I had problems getting it to work with XCode and found this help:

Topic : iPhone OS 3.0.1 does not work with xCode

http://discussions.apple.com/thread.jspa?threadID=2103502&tstart=0

So I ran this and it seemed to work.

ln -s /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0\ \(7A341\) /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0.1

The symbolic link no longer works so just wondering should I delete it.

Some notes on my installation layout I have these installation directories:

Developer:                3.1.3 - works - app in AppStore
Developer3_2_Final:
Developer_4_0_Final_Xcode3_2_3:
Developer_Xcode3_2_3_iOS_SDK_4_0_1:    This is the version that crashes

The only symbolic link I created was under /Developer yet crash caused when I use Xcode in /Developer_Xcode3_2_3_iOS_SDK_4_0_1

My app was built in 3.1.3 using /Developer so am loath to remove it.

not a unix guru though am willing to dive in so any pointers gratefully received.

The /Developer_Xcode3_2_3_iOS_SDK_4_0_1 was installed yesterday and I ran the 3.1.3 against it and then debugger when running on device crashed.

So I have done nothing with any of these SDKs except create that symlink months ago and install SDKs above 3.1.3 in seperate directories till I was sure I could build against them.
