i8000 users on ATT northern america network

[Guest melmobile]

After a few week of usage. I found out I have a lot of drop calls in many area in San Francisco. Here's how my i8000 acts up and want to see if it happens to you too...

1) phone mode will be turn off by itself. you will have to manually turn it back on otherwise it will stay at flight mode. usually happen after a drop call.

2) you try to make a phone call, it connects for 1 sec, you hear the ringing tone then it gets cut off immediately.

3) when other party calls u, you press the green button to receive phone calls, and then it gets cut off immediately.

solution, i will have to turn the phone off and turn it back on in order to make the phone mode works again.

any expert out there to help? anyone experiences this?
