Dubs do you have tmobile now? And you can unlock the sidekick, but I dont see why you would want to, all you can do after the unlock is make calls and send texts. Danger has a 5 year contract with tmobile for exclusivity, its like 3.5 years into that. You might see the sidekick NG for both, which should come out in a year and a half.
Future: Another mazda3, maybe a P5..
Current: 2007 VW GTI PKG. 1 FOR SALE
Past: 2007 Mazda3 5-door, 2006 Mazda3 Sedan
