Google G1 Problem: How do I set up my phone after I reset the factory settings?
I rebooted My Google G1 phone to factory settings so you can start over. But when it comes to the stage where I need to create a Google account keeps saying a new you can not connect to Google's servers, because there is a connection problem or problems with my SIM card. That do now?
If you can see the data connection icon at the top? If you do not need to call your provider TMobile? to see if they can resolve this problem. if you call directly to request an android / Specialist late because the IT guys seem pretty ordinary or idea of the data connection to the android. That's what I do when I got my myTouch.
