I live in Canada and I know someone who is heading to the US who could pick me up and iphone. I know most likely I will wind up with a 1.1.2 firmware version which can be jailbroken, but not use any sim. Now my questions. 1.)When a fix for 1.1.2 is released is there anyway to turn off the edge service so It's never in use? 2.)If I have the edge service turned off can I still send text messages and use all the other apps just using wifi? Thanks for any help.
