I had a blackberry all of last year and switched to a pda for a few months, now im back to the blackberry...but a different model....now it says my @mycingular.blackberry.net addy is taken...how can I get it back?

Call Cingular customer service... They will 3 way call you RIM and can reactivate the addy.... At least that's what T-Mo did for me....

The addy is most probably still taken by you.....

That's usually the case.
It's kind of locked until you have them unlock it and then you can take it again...
I had to do that on Cingular and it worked.. just took a phone call and some patience.

yep
