G1 issues please help!!!

[kryptikhonor80]

I have the HTC G1 Google phone through T-Mobile, But i had it unlocked to work through AT&T and it ran fine before I had to do a master reset on it due to 3 failed login attempts on the draw pattern lock feature...I did the master reset and put my ATT card back in the phone and its now telling me that I have no network connection. I have called TMOBILE and ATT both and they both told me to call the other. Total waste of time...can sumone please help?!

Starting with the most obvious: have you tried another SIM in your phone? Have you tried your current SIM in another phone?

Have you done menu > settings > wireless controls > mobile networks > network operators? When I do, both T-mo and AT&T appear. If they don't perhaps your APNs are wrong?

But... you do have AT&T data/voice plans? Maybe someone else can walk you through the APN settings if that's it.

See if this helps with your apn settings.
