xda-developers has a very good testing collection. I have tested 3 so far, 2 of them with working WAP (on MetroPCS) I flashed the phone to MetroPCS so I don't get google maps or market
But if you have Sprint you can enjoy more stuff. Bluetooth works on 1 of the builds I tested. GPS works on 1 of the builds as well but no internet so it's no good on MetroPCS.
