I noticed mine crashing once in awhile and this is brand new bought it a few days ago I think it's mostly safari and a couple of games that crashed. Idk wats goin on but I'm glad I'm not the only one. It's just a rare occasion for me.
Safari on mine has been crashing a lot. Someone on Social Hut told me to clear the multitasking bar just last night. And it hasn't crashed ever since, well maybe like just before I went to bed I cleared it. And if you don't know what Social Hut is, it's the best place to chat. iPhonefreaks forum! Please join!
