I had T-Mobile and moved to an area with no access. I switched to AT&T. Before I left I received the unlock code from T-Mobile and applied it successfully. I then put the phone aside and used the MyTouch phone I also had. Now I am interested in using the G1 also and I have a problem.

This is my problem. I boot the device and I am prompted with three options.
1. Create a new Google account
2. Log into an existing account
3. Place an emergency call

I tried logging into an existing account many times and then tried creating a new one. All attempts failed with the error "There is a problem communicating with the Google servers". I understand that I may need to create an APN for data stuff but I don't believe I need to create one to simply log into the Google account.

I currently have a data plan with AT&T and it works fine on my MyTouch phone because I created the custom APN. It, however, did not need the APN to log into Google initially so I am assuming it isn't required for the G1.

If I am wrong here then how can I enter/create an APN without first logging into the Google account thus making the phone interface viewable. I'm confused on how to proceed and would greatly appreciate any assistance.

TIA
