This happened all of a sudden, I hadnt done anything suspicious or wrong, i was playing a game the other day and when i wanted to turn on the iphone, it was showing me the slide for emergency screen with the modern itunes logo, anyone can help me get past this?

You'll need to connect the phone to iTunes. If you're jailbroken, you may be able to just complete a tethered boot. If you're not jailbroken, then it's likely that something has gone wrong and you need a restore to sort it out.

really aprreciate you replying to me, the reason I havent replied in a long while is that after a week with the iphone like this trying the itunes restore thing, i just gave up and left it like this for a month,then when i decided to charge it (battery was zero) and turn it on again, it miraculously worked like normal, there was no slide for emergency screen. but then, it happened again after a few days when ive turned off the iphone a couple of times and now i dont want to wait over a month again! So, can you tell me how i can successfully complete a tethered boot? thanks
