I pre-ordered 2 iphone 5's friday 4/5/2013 but had a credit card issue -- had to re-order them 4/10/2013. They transferred my cancelled order over and shipped my phone 4/11/2013 -- and I received it 24 hours later 4/12. The service was immediate and so was the carrier update. Straight talk was taking their time porting my phone number over, so they called them with me on the line -- and within 3 minutes I had my phone number ported over. I'm getting full bars & about HSPA+ 15 mbps at home in San Diego, CA -- where I used to get no more than 2-3 bars with AT&T/simple talk and no more than 2-3 mbps. In short, I'm extremely happy with my switch back to t-mobile, as I had them 4 years ago with my blackberry. If you have any doubts about their network in SoCal, worry no more!
