Google G1 Problem: How do i set my phone up after i restarted it to factory settings?

I restarted my Google G1 phone to factory settings so i can start over fresh. But when it get to the step where i have to create a new google account it keeps saying that they can not connect with Google's servers because there is a connection problem or its a problem with my SIM card. What do i do now?|||are you able to see the data connection icon at the top? If you don't you need to call your provider tmobile? to see if they can fix it. if you call ask directly for a android/blackberry specialist because the regular I.T. guys seem pretty clueless about the data connection for android. Its what i had to do when i first got my mytouch.
