Update: Ok, updating took about five or six minutes. Noticing anything specifically? Let us know in comments, we'll list the fixes here (since Apple wasn't courteous enough to tell us what, exactly, it repaired in the device).
Ah, Apple's added the fix / changelog. Noice! Just looks like Safari-related security updates. That's fine and good, now howsabout the constant, mind-popping crashing going on with that app?
Oh, and good news everybody! iFuntastic (v2) still functions with the 1.0.1 update! We tested it, and it worked beautifully.
Also, is it just us or did all these Safari security fixes come along with stability fixes as well? We've never seen mobile Safari perform so admirably with eight full ajaxy pages open as we have since loading up 1.0.1.
