I upgraded to 2.1 due to general lag and slowness with the jailbroken 2.0. I had numeric battery, carrier name change, and other things installed. I upgraded to 2.1, and restored from my previous backup to get my contacts, texts, mail, calendar and all. Carrier name is still changed, still displays numeric battery....is thing because of the backup i used? I didn't know if this happened to anyone else.
