Yesterday afternoon, Safari began to lock up. I hadn't tinkered or just added/run any new apps/settings/bookmarks that might have led to this. I was in Safari and tried enter a URL. When I selected the appropriate box, as soon as I touched the keyboard, Safari froze. Pressing the home button took me home, and selecting Safari worked. Sort of. It would open Safari, and the page I was on would reload. If I tried going to a URL again, it would freeze. I went out again, and tried the search box - same result of freezing. After force restarting, Safari opened by going directly to my bookmarks rather than just giving me a blank page. If I closed that window and tried to enter a URL or search, freeze again immediately. If I selected a bookmark, it would open. I reset the phone and got the same results. I tried doing a restore, and again got the same results. Sort of. After the restore, Safari worked at first. I went to bad and this morning Safari began crashing again. I called APLCARE and have two appointments for tomorrow (I made two since I'm not sure where in town I'll be when). Phone guy said it sounded like a hardware issue, but he also didn't know about the iPhone availability chart - he wasn't sure if the stores could do a swap since he had "no way to know if they are in stock." I just cleared my cache/cookies/history, and Safari is working again, but I'm waiting for another fail. I'm just wondering if this has happened to anybody else, and what you did to correct it - was clearing the cache enough, is there another fix, or should I go to an appointment and press for a swap?
