I'm aware of the 6.15 iPad baseband messing up the GPS on the 3GS / iOs 5.0.1 BUT will it do the same thing on a 4G? I'm willing to live with a hosed GPS even on a 4G. Someone has one for sale on CL and I'm considering buying it. Can I even upgrade the baseband to 6.15 if they are sitting with the latest and creates IOS and baseband?? So in summary I plan to buy a iPhone 4G off CL, use the latest version of Rebsnow or pwnage tool to jailbreak and unlock via Ultrasnow AND in the process hose the GPS which is fine by me - will this work ????????
