Here's what I did.... I was one of the dummies who updated to iTunes 7.6 and 1.1.3 firmware. So I downgraded to 1.1.1, jailbroke it, upgraded to 1.1.2, then 1.1.3 with iPhone apps. Everything worked fine until I started to add the fourth or fifth 3rd party app. Now Installer crashes every time I try to open it. I installed Oktoprep, systems, and OpenSSH. Did I miss something? Does anyone have a solution for me, other than starting over by downgrading and upgrading once again????
