Hi. I currently have Sprint 1500 Family Everything Data Plan on 4 phones. $129 plus 40 for the other two lines. I am evaluating the HTC Hero for 30 days and the G1 looks just as good, so since my Sprint contract will be up soon, I am looking at my options. What is the best Family Plan for 4 phones on T-Mobil for around 1500 shared minutes? I need texting on all 4 lines. Will be happy with just wi-fi access for Internet.
