i decided last night to attempt to update to the new OS for the first time from .75. i followed the instructions and backed up my phone, and then after that backed up my applications by clicking device switch manager. when this was done i had to put in a name and pin, i believe, and i wasnt able to find a name (and without that i couldnt enter my pin). i decided to try this step again, but when it took too long, i cancelled. now my phone is telling me that my radio is off, and on the top right corner i see there is no signal. how can i fix this? i didnt actually upgrade the OS or anything so i didnt think there would be a problem.
