What I want: 4G, latest Andriod (2.3.3?) smartphone suited for my uses: (ordered from most common uses to least) internet, games, tethering, programming/development, apps, calls, IM. I think the most suited phone for me is the Xperia Play. I believe that I'll meeet 100 minutes, 20 texts, and 2GB a month. I want to save money where I can. I want the most cost efficient way to get it so, here's my plan: 1. buy unlocked GSM white Xperia Play, UK imported (~$450) 2. buy T-Mobile SIM card + Whenever minutes (~$10/month) 3. buy AT&T 2GB data plan, upgrade to tethering when needed, use 15% employee discount ($21.25-->$38.25/month) I am doing it this way instead of contracting with Verzion because I think I can save money by avoiding a talk plan by using T-Mobile's prepaid minutes. Xperia Play using a T-Mobile SIM card is only available through AT&T, which also offers the cheapest data plan, so I need to stick with them. Are there any faults to this idea? Are there any restrictions that I should know about that will prevent this plan from working? Am I really saving money?
