Hey guys, Just thought i'd share my story with you guys. My iPhone 5 I got on launch day was really burning through my data package, despite being on WiFi. I took it to my local Apple store, and they hesitantly replaced it. I had to fight for a few minutes to sway the "genius" from thinking my iPhone wasn't defective. I ended up getting a new iPhone, and an Otterbox Commuter case. Couldn't be happier. The new iPhone uses about the same data as the 4S, and not burning 300MB every three days. I am also getting fairly faster WiFi speeds, 15Mbps as opposed to 6 on the old device. It is a newer (i guess) ND097LL/A Model with the same exact serial number. My advice to you guys is if your iPhone is having the same issues that were in a few of these threads, take it back, and get a replacement. Just wanted to share my experience with you guys!
