flash 6900 htc picking up other networks

[atltopdog]

i have a flashed htc touch that is on metro pcs. i had it flashed over at one of the metro stores here in atlanta. i have a few problems i need help with.

1. the phone works fine when im at home. but, when i go to other parts of town thats on the extended metro network, the phone says that im on the cricket network and unable to make a call. i use my flash utc starcom in the same areas and it works fine.

would my sid cause this to happen? i checked it and my sid was for texas, but even then a texas metro supposed to work in atlanta.

2. how do i keep my web from resetting when i cut my phone off or reboot?

3. has anyone gotte mms to work yet. ive tried every thing on the boards and nothing has worked for me
