I was also came to the GS2 from the Evo and the GPS & battery failings were immediately a source of displeasure. Unfortunately, the ‘Connections Optimizer’ tool that was added a couple of updates ago has really shone a light on the network’s signal strength where I might otherwise not have noticed the antenna switching.
The location in question is NYC, Manhattan mostly, and if their Wimax roll-out is any example, it’s not a market in which Sprint has traditionally put a lot of effort to lead “straight out of the gate.”
The truth is, I know I have to switch with my next phone as my expectations of reliability have changed. I hoped I may have waited it out long enough but I haven’t and I simply can’t suffer through another network roll-out. It’s like hopping around on beams while someone is installing the floor beneath you, except I’m paying money for the pleasure.
