I'm upgrading from my current Galaxy S2 Skyrocket on AT&T. Yeah I'll lose LTE but I'm betting it'll be worth it for the upgraded phone. I've only had the Skyrocket for 13 months and had no intention of upgrading this early but lately I've had some weird hardware problems with the Skyrocket. While using it, or just sitting idle, it will shut off, start to vibrate in pulses, the camera flash will go off in pulses, all of this for 30-45 seconds and then it will reboot. So yeah. I didn't think I had any options to switch phones other than to try insurance claim through AT&T but then again you usually get refurbished phones. Why pay the $200 deductible for that when for a little more get the unlocked Nexus 4? Looking forward to owning my first Nexus phone!
