Need to restore 3GS running 3.0.1 jailbroken with old bootrom and old baseband.
Are there any options to not loose the unlock but upgrade to the 3.1.3? I have 3.0, 3.1, 3.1.2, and 3.1.3 SHSH's on file with Cydia. My phone is acting up and draining the hell out of the battery, figure I need to restore but dont want to give up the ability to unlock.
You can strip the baseband update from 3.1.2 by using a program but I can't remember the name right off hand. It has something to do with cold or ice...and there's also a way to do something similar with the newest redsnow. Get on redmondpie and there will be step by step instructions on what to do.
