I have an OOB 1.1.1 with the 3.9 BL and I just upgraded to 1.1.4 using Independence. Everything worked, except now my Mail.app crashes whenever I open it. It displays a blank mail screen for a few seconds, and then returns to the Springboard. I've tried disabling sync on iTunes and deleting my mail accounts, to no avail. Does anyone have a solution for this?
