I don't know much about all this upgrading stuff.
I own an 8800. I got it last month.
I've read that BB released a new OS. Does the upgrade apply to my 8800 from AT&T, too? Currently, when I go to [options] [about], it says: v4.2.1.72 (Platform 2.3.0.54)
Do I already have latest software?
Also, what are the changes in the new software? Will the themes no longer say "Cingular" on them? Are the changes just visible ones or what? Please explain.
