The best cell carrier by far. I can't believe that a AT&T merger is underway and I prey it is blocked. T-Mobile will bend over backwards to make sure you are a really happy customer. The service (phone and data) is amazing.
The other day I was talking to a co-worker. She has a iPhone 4g on AT&T. My 3G Samsung Galaxy S Vibrant is faster; much faster! Loading the same YouTube video I started playing after 3 seconds from click, she started playing 8 seconds after click and paused for 3 seconds to CACHE during play; of course I did not :)
Pricing, customer care, phone selection, voice quality, lack of dropped calls, fast reliable internet; what else could you possibly ask for?
