In case the upcoming iPhone 5 is on Sprint, I would like existing sprint users to tell me how much service there is in the san francisco bay area. I am currently on an AT&T family plan with unlimited messaging. I have an iPhone 3GS with no data plan because I got it used (and for free, thank god for parents' friends). I will get a 4GB data plan. How's the service in the bay area for sprint and is the pricing any good compared to what my parents are paying? I would like the $69.99 plan on sprint if they get the iPhone 5 (or 4s). Can someone help me with my questions?
