LG Optimus LTE 2 (in Korea)
I have had this phone since June 6th.
The only time I have been able to lag this baby is when I am downloading 4 or 5 videos from tubemate simultaneously over wifi.
Once i was playing a video with the screen at full power.some warning messages said i might overheat the screen.
The web is full of specs for this phone.
If you have any questions...ask away.
