AT&T will get the version of the Optimus G that sports an 8-megapixel camera. (Other regions are getting a 13MP shooter.) That makes a difference, because the 8MP camera is flush with the body of the phone, whereas the 13MP lens sticks out slightly. Sprint says it'll carry the 13-megapixel version. (See our pre-production Optimus G camera test.)
Both phones will run on their respective carriers' 4G LTE networks and sport the Qualcomm Snapdragon S4 pro processor at 1.5 GHz. They've got 2 gigabytes of RAM and a 2100 mAh battery. AT&T's phone will have 32GB of storage, as will Sprint's.
No word on pricing or availability yet for either carrier.
We've got hands-on video and more pics after the break.
