I hadn't seen this anywhere else. From geekfor.me i saw there was a new radio update,So i checked my radio and it was the old one. So i downloaded and followed the instructions. which in indianapolis i would get horrible reception after doing the radio update i have like all full bars and a constant 3g. Got all the info from the website
http://geekfor.me/
i had zero issues when using their instructions worked perfectly.
Haven't checked to see if i get a better battery but just a better signal is amazing.
