My sister was updating her iPhone when she got spooked by the update (thinking it was a virus! -stupid I know!) so she turned her phone off. Now the iPhone won't boot up and it's also not being recognized on her laptop. The white apple with black background will appear but it then slowly turns white and stays like that until I try to turn it off. She's tried her sim card in another phone and only half the contacts show up (A-J) - does this mean the sim card is corrupt or just that it ran out to room to save her contacts to her iPhone? Any ideas? I'm desperate and any help would be greatly appreciated.
