3B-16GB, FW 3.1.2, BB 4.26.x, Pwn'd:

I added a new source to Cydia. During the black-screen download of the packages, Cydia crashed to the Apple logo. Waited a few minutes -- nothing. Power/Home to force a turn off. Tried again. Same. Third time was a charm. It booted into safe mode. Restarted. Rebooted. Whew --- it's really working again.

............ BUT ......................

ALL of the Apple Store apps would crash on open.
Stock Apple apps and Cydia apps were OK.

(no way was I going to restore --- this was bull crapola (I hope )

The FIX! (One of the following - I did both at the same time)

1. Delete an Apple Store app, and re-download from the iPhone AppStore.
..... and / or .....
2. Connect to iTunes (don't sync or anything -- just connect).

Once I did this ALL the remaining AppleStore apps worked.

Any ideas what really fixed this?
Did my 'Apple Authorization' get messed up?
Did reentering my password fix it?
................ or ...........
was it the connection to iTunes?
Geese I hope not iTunes. What if I'm traveling without my computer. Ugggg.
