Just went to the Android system. Basically it was a cost issue. I have been with Verizon for many years. I went in to the Verizon store to get three iPhones and a data plan for the family. $800 up front and $200 per month for 700 minutes talk, unlimited msg., and 2GB data (per phone).
Went to the T-mobile store and got 2 HTC Sensations and one HTC Wildfire for $600 up front and $140 per month, 1000 minutes talk, unlimited msg. and unlimited data (2GB per phone per month at 4G then it drops to 3G speed).
Both 2 year plans. Couldn't be happier with the phones. Just like and iPad but smaller and makes phone calls.
The HTC Sensation with its dual core processor and a 4G signal is as fast as my DSL line at home.
