I've gotten the runaround from Sprint about the Network Vision rollout since March. They were saying it would be completed for my area (I'm inside the DC metro area) by late June. No change as of today, just terrible 3G data speeds. They pushed that date back to December apparently, according to my most recent call to them.
I'm dropping Sprint to get the iPhone 5 on Verizon. I have Verizon service for my new iPad, and the LTE speeds are RIDICULOUS, like, better than my home cable internet connection. I can't wait to have that speed everywhere, with my phone. Plus I save money having my phone and tablet on a data share plan (vs the Sprint plan and separate Verizon plan I have now). I may be one of the few people that these new data share plans actually help rather than hurt.
I'll miss the concept of unlimited data, but, what was the point of it? The speeds and coverage were so terrible, it didn't really matter. Sure Sprint will rollout LTE to my area somewhere in 2013, but I don't want to keep giving them money every month for terrible service, while hoping it eventually gets better.
Oh and paying the ETF sucks too, but selling the 4S covers most of that thankfully.
