After massive amounts of researching I decided on this phone. ATT's gsm coverage is horrid in central Phoenix so I took back the tiny T616. I have always heard that the Sprint coverage in Phoenix was very good with excellent call quality. Well...not for me. I live near downtown and barely get a signal inside my house. At 7ave &amp; McDowell I rec'd &quot;no svc available, try analog&quot;. This is not acceptable. Everybody I talk with say that they hear me very clearly, but it's not the same on my end. I thought it might be the speaker on the phone, but I returned it and tried another. The calls are consistently fair to poor. It sounds like the other person is on a cell phone being held by their head. They aren't. I'm still within my 2 week trial on this one, so I'll probably return it. I'm at a loss as to what to try next. The next choice is Verizon with the LG VX6000, but I don't like their calling plans. I'm afraid that T-Mobile's gsm service will be as crappy as ATT's. Why can't one of these companies make a camera phone with speakerphone and/or bluetooth that actually provides good reception. I don't know anyone that needs a 1000 number of phonebook entries, but I guess that's easier.
