I removed some apps from /system/app

AdService.apk and AdService.odex is needed for Android Market / Google Play

blur_yahoo.apk and blur_yahoo.odex should not be deleted or contacts app crash (force close)

Update:

BlurEmailEngine.apk && BlurEmailEngine.odex needed by SMS/MMS app

The included swype (dated version)can be removed, but you also have to remove a library so file.

To remove swype keyboard
Delete:
/system/app/Swype.apk
/system/lib/libSwypecore.so
