The 3G internet on my iPhone 4 isn't working properly.
It'll search for a while and then it'll say no service. I dropped my phone a few weeks ago and it hasn't worked properly since then. Strangely, I went to London a while ago after the incident (about 2 hours away from where I live), and it worked fine while i was tgere, then once I was back home it didn't work again. I've tried rebooting and all sorts but nothing has worked. What should I do? I bought my phone second hand so would I still be able to send it to apple to have it repaired?
iPhone 4, iOS 7.0.6
