before 1.1.1 I had a iPhone unlocked with the baseband corrupting free unlock solution. Then 1.1.1 came along and I decided to cough up the cash to do a proper sim unlock. Trouble is my battery life has been very bad since the upgrade. I suspect that one of the programs used during the unlocking process might have left something behind that is eating up juice. First of all is it safe to do a restore to 1.1.1 again (I have the firmware file) via iTunes on my iPhone? I have not seen it mentioned anywhere. If I restore to 1.1.1 via iTunes will the sim still be unlocked and I would only need to do a new jail brake? Secondly does a restore truly wipe everything out and do a complete wipe of all files on the iPhone or do I have to resort to more extreme measures? I don't want to run third party programs since I don't need that crap on my phone, I just want to be able to put my sim in it and use it. I don't want anything Apple did not ship with the phone to stick around in there and maybe crap things up.
