my iphone 4s shuts off automatically, and i can't turn it on with just the power button i need to do the "reset" all the time. it's been happening since sunday and today is already tuesday. what is happening?

Hi, thank you very much for your reply. No my phone was never been jailbreak-ed. Never been dropped in water or in any wet surface. Dropped on the floor while texting yes, but it was just a one time incident, last year august i can clearly remember, but after that no more (phone still works fine even after.) restored the phone again earlier, but problem still occured. Will try to go to Apple also to ask and have it checked. Just worried because my phone is already out of warranty. Will keep you posted. Again, thanks. If you have any more advice just let me know. It would mean a lot.

Cheers,

N
