Was Safari crashing before the update? The reason why I ask is because from the time that I bought my iphone and upgraded to 1.0.2 Safari would crash at least every 4 times and Google maps would crash every 2nd time. It was really annoying. I felt like it should work better than that. I called apple care and the guy said that there were two steps they would try, the first was to do a complete restore and the second was if the restore didn't work, they would need me to send it in for repair. Anyway, I plugged my iPhone into my computer and in the itunes window that displays your iPhone I clicked restore. It wiped my phone and loaded a complete new version of the OS. That was 3 weeks ago and not one program has locked up or crashed since. My advice is to try a complete restore of the 1.1.1 OS by clicking "restore" in the itunes window. Be sure that you back up your calendars, contacts, bookmarks, and photos before you do this. Hope this helps.
