I got the 4, I have on office on the edge of service/Roam, and it wouldn't work. Repair Center denied any problem, so I jumpted to ATT.
Retentions decided to send me new Pre if I would stay along with a temp line to test.
First, my new Pre worked great but wanted to see the Iphone 4.
Got my Iphone on Wed, had fits activating. Then found the salesman "mislead" me on my programs, needed to spend more money to kinda get close to my Sprint programs. Thinking on this, was really getting unexcited about unlimited calling, data, paying for Navigation then using data so I could pay even more, eliminted MHS, eliminated any streaming.
Finally I looked at the bar situation - holding my new phone normally, I went from 5 bars to 2, -3. My problem area starts at 3, so think what the results are!! So for the extra $1000 a year cost with so many restrictions, no brainer.
Going back today, love my Pre and realized after playing with the Iphone, its no cooler, definitely not easier to use, and I don't want it.
However, I can understand why the masses love it, a lot of our Pre's are based on it and for that reason, should be happy for their users.
