Mrs. jsnydcsa and I have been with T-Mo since the Voicestream days we've wanted iPhone's for some time and were longing for T-Mo to join the fold.

Our 3+ year old Blackberries are starting to give up the ghost and we've suffered some major CS lapses from T-Mo in the last 6-12 months or so. Plus, we've seen a bit of bill creep over the years (my fault, not T-Mo's, I know) that has pretty much made our T-Mo bill nearly equal to projected Verizon bill with two new iPhones.

While I've always appreciated T-Mo's cheap turn-on/turn-off international email (formerly all data) roaming, I'll miss it when we switch over (likely to Verizon) to iPhone 5.
