I'm on a grandfathered unlimited family plan with 2 iPhones. As soon as tmobile gets their 3G iPhone service up in my area I'm paying my ETF and jumping ship. I did the math and I'll save over $1000 on service over the two years, even if I buy an iPhone unlocked at full price. I'll get my wife an Android phone because she doesn't really care as long as she gets her email. The tmobile plan will get me 1000 minutes, unlimited texting, and unlimited data (2gb high speed, which is plenty for our usage) for $79/month. That compares to the $150 something were paying now.
