after hard reset GPRS internet no longer working

[Guest mlinzer]

I had to hard reset the phone (unlocked), and redefined all GPRS internet settings, but the thing will not connect ("The remote party has ended the connection"). Tried installing all the unlock apps, to no avail. GPS does not seem to be working either. Can it be that something got locked up after the hard reset? Tried removing the predefined AT&T connections, does not seem to help. Any more ideas?

Thanks,

Moshe
