Of all the various things that folks have complained about on this phone, the lack of simultaneous voice/data in 3g areas is an absolute deal-breaker for me. I could deal with 11 Gig of usable space and a sealed battery, but what i cannot deal with is working in rural areas of Michigan and not being able to function as well as I can with the Thunderbolt. (Can't believe I just said that.) I find myself talking & searching maps or technical documents all the time. If I couldn't do both simultaneously, I'd be hosed.
