Hi all! So, yeah... jumped in feet first to the iOS7 beta. Figured it may not work because of my own failings; but it seems I've run into something unexpected. I have an AT&T account, and purchased an iPhone 5 through Apple.com when it came out. A few months later, the sleep button was giving me issue. I brought it in, they exchanged it with a refurbished unit right then and there. Great. Fast forward to tonight, and I'm getting a "This iPhone is not currently setup to work with carrier you're attempting to use..." error. I'm stumped. I've never jailbroken. I have AT&T. I have an AT&T sim. It worked fine on iOS6 earlier today. So, I do some digging. End up paying a dollar to some site to email me phone details based on the IMEI: I get this: First Activation Date: 10/11/12 Last Activation Date: 10/11/12 CTN: 18168081158 Carrier/Next Tether: Canada Fido N41. SIM LOCK: Locked Pretty sure October 11th is when I got the refurb... and it says SIM locked to "Canada Fido N41" ... whatever the heck that is, lol. Any tips or tricks to solve the issue, or am I screwed right now? I've set up a genius bar appointment for 10am tomorrow; I imagine they'll end up working some magic on their end, or hooking me up with a new phone? Thanks!
