Please do NOT download the latest software update ios 6.1.1. My friend has done this and it appears to have wrecked his iPhone5! He has been in the Orange shop twice and the Apple shop twice today. Phone is just over 12 months old so out of warranty. Had new sim card, been reset several times etc but all to no avail. Apple are trying to say the phone must have had a hidden fault in the 1st place for the software update to have broken the phone. AIBU to expect Apple to hold their hands up and take responsibility for either repairing or replacing phone? Crap customer service!
