has calmed down a bit.
I haven't dug through this thread, but some of the folks here might be able to help

hmm, went through the thread and I have the Nokia care suite, but there aren't any at&t roms :'(
Seems like I'm stuck now. Anybody know if the at&t stores have the ability to flash these phones?
Edit: it fixed itself, its all good now. I just left it running and it finally booted to the welcome screen. Completely random, I'd left it spinning for much longer previously. Thanks for the help, everyone, much appreciated.
