How does one go about unlocking carrier specific apps? I have seen a supposedly unlocked .apk for the new verizon NFL Mobile (haven't tried it though as I am on Verizon). I'm interested in trying the same thing with Sprint's Nascar app for use on Verizon. I've searched but can't seem to find one out there. I have found the .apk, but of course it tells me I must be on Sprint to use it. Thanks for the info guys.
