Managed to really fuck my phone up today - no internet works on it so took it into the O2 shop and they said I need to the Apple Store but I didn't have time. But it's only £100 to upgrade to a iPhone 6 with unlimited data. Do you reckon it will be worth upgrading it (or even to a different type of phone) as I have a feeling Apple will charge high prices for repairs.

Also being the idiot I am decided to reset it to factory defaults instead of just the settings so lost the apps and all of my contacts which has really pissed me off
