I am on T-mobile and I am kinda fed up how I get almost NO signal in my household. When I leave my house its perfect but in my house I miss countless calls/texts. Also since I got Tmobile I don't have 3G for my 3gs. I just got another 3GS lastnight, 3.4.4 Ver with 5.16.02 Firmware and want to go into AT&T see what they can offer as a plan for me. I am not looking sign a contract at all(waiting on IP5), I currently pay $100 total for Tmobile, unlimited everything. If I can get same for AT&T for around $120 I will make the switch. Any tips/tricks I should know before I walk in to try get the BEST deal possible. Am willing to paypal someone $10.00 if they give me Information through PM that can't be said publicly and works to save me money. Thanks! Edit* Is there a difference which Store I go to?
