I bought a SE K710i in the Amsterdam airport yesterday. Cool phone. This thing gets amazing coverage! I can use it anywhere in my house. Any other phone will only register onto T-Mobile in the kitchen and its only usable in one spot. I just cannot believe the difference. Since Cingular now has 2 sites blasting 850 into my house within 1 or 2 miles I thought I was lucky to get any TM service inside (T-Mobile tower is 3 miles away). I haven't used the mp3 player yet. I had bad luck with my first Cingular SE (that bar phone...cant remember the #), and had mediocre service with that SE swivel phone last summer (05) though it had a great camera. I think I am a SE convert now!
I'm comparing with a RAZR, Moto v190, and the t609. Surprising the t609 was the best out of those three. The RAZR was the worst. It held calls fine, but would lose signal much faster than the others and lock onto the tempting, yet banned, (att?) Cingular 850.
