I have a jailbroken 1st Generation iphone running on T-mobile I upgraded to 3.0 last night with Redsn0w and none of my apps will work any more. They all required an update (which I did) and I've rebooted several times and still everything crashes instantly. I've tried reinstalling and even downloading 3.0 apps I did not have prior to the upgrade and they won't work either. Has anyone had this problem? Thanks!!
