t-mobile sucks but so do iphones that's what they just CAN'T put the 2 together or we'd all die.
Not a lot of good "Seahawks" apps out there. The official one is cool. Listen to pinksheets, follow all the right people on Twitter and you can have all Seahawks talk all the time. Combine that with .NET and you'll have to forcefully make time in your life for anything else.
If you're into games download NFL Flick Quarterback. The gameplay kinda sucks but it looks awesome and you get to be the Seahawks which is all that really matters, right?
