I don't know why but every now and again my iphone acts up. All of my apps crash upon the start up, and if I restart my phone it gets stuck on the apple logo. But, of course this is very annoying and the only apps that work are the apple made ones (Default apps) -if anyone can help me with this plz PM or post! Thanks.
well, this has happened to my grandma. try deleting a third party app then re install it, that's what fixe my grandma's iphone. that or a restore, the more likely of these two solutions.
