Same problem here marketplace just gives a server error, any advise?
Using the v4 rom, I get the same problem. I can enter my account info and read the ToS, but after that, all I get is a server error. There was a marketplace update in mid December. I went and pulled down the 2.2.7 release for Android 2.1 and installed it via ADB. After clearing all data on the device the following sequence occurs.
Prompted for Google login credentials
Login succeeds and I get booted back to the home screen.
I get prompted to accept the TOS
Booted back to home screen
Get "A server error has occurred. Retry, or cancel and return to the previous screen."
