Hey guys. There are threads on this but I really haven't seen a clear cut answer... so here I am. After so long, I reached out and bought an iPhone from the AT&T store when they had the refurbs up. I couldn't pass it up. So, currently I have T-Mobile and my month ends on April 4th, and was wondering if you guys could please give me some advice. I think I was a Cingular customer way back in the day, but would be signing up to AT&T new of course. When signing up, if I want to retain my current cell phone number (the one on tmobile) and use that on AT&T, am I able to do that by registering through iTunes? or should I just go to the store. Also, if I register on iTunes, I would assume that there's no Activation fee, or would there be? and lastly, on all my other phone plans I've been receiving a discount for being a Government employee....... does AT&T grant this as well? I imagine not though for some reason. Well, that's all for now. Any help would be appreciated!
