i am one of the unlucky ones who have the alarm problem since dst. it goes off an hour early. so ive been thinking of re jailbreaking on 4.2.1 to see if it fixes the problem. should i try this or wait for 4.3? i have my shsh saved in cydia for 4.2.1. or does anyone else know a good fix for the alarm problem?? if not, is the best way to do this is to backup my iphone4, then use tinyu to upgrade to 4.2.1, then use greenpoison to jb again?
