Okay, I've got a 4S, I'm at student, with no money to replace it.. I'm in the UK, and i've only had it since october, since late november, I've had problems with losing signal for about 30 mins each time (at least), the phone cutting me off and having sound problems during calls, lagging keyboard and yesterday there were purple and black lines all over the screen before the screen died.. it just went black, I got what I assume was a text, as it vibrated but the screen meant i couldn't read it; then i tried to plug it in and do a restore and then the apple logo came on, flickered and now the phone won't do anything at all 
Does all that warrent a replacement? I've got the box, the reciept, everything. I'm no where near halfway into a 2 year contract, can't afford a new one, will they believe me? There are also no genius appointments available anywhere where I live (in London) so would I have to try and just walk in and see? I'm so so stressed, I'd be so grateful for advice
