XCode 3.1.4+debug iphone 2.2.1 = iphone reboot :(

Hi, i have a jailbroken ipod touch 2g running 2.2.1 firm.
I am writing a simple app in Xcode 3.1.4 and when i hit build and go to put it in the device, right when it installs it and runs it, my ipod reboots and goes to safe mode and i get the broken pipe error in xcode.
If i ssh into the ipod and ldid the app then it works fine.

Anyone knows why it does that ? or even better how to fix it ?

Some info about my xcode details:
- I have added the singeridentity....in my project's info.plst
- I have made an iPhone Developer certificate, self-signed..
- I have added the _ALLOWED, _REQUIRED entries in the iphoneOS.platform .... info file.

Thanks.

Fixed it by doing this :

- Download gen_entitlements.py
- Place it somewhere in your mac ex. /Users/youruser/gen_entitlements.py
- Open a console, go there and type chmod 777 gen_entitlements.py
- Open Xcode and go to Projects->New Build Phase->New Run script Build phase and paste this:

PHP Code:

---

export CODESIGN_ALLOCATE=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate
if [ "${PLATFORM_NAME}" == "iphoneos" ]; then
    /Users/youruser/bin/gen_entitlements.py "my.company.${PROJECT_NAME}" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent";
    codesign -f -s "iPhone developer" --resource-rules "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/ResourceRules.plist" \
         --entitlements "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent"  "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/"
fi

Dont forget to edit this and add the proper path where your .py is.

- Build a go and you are ready to go :)
