OK, it looks like both cLK and MAGLDR versions have the same problem now - only wifi data works once you flash the app. Of course each could have a unique cause.
I will try to get a logcat later tonight. It's not so easy because my son is now using the phone that had been my spare for testing and he isn't home much.
If anyone else can post logs as Tytung asked, please do so. I'm sure he would be happy to move forward once he as something to work with.
