A:
Although there are many differences between the Sprint version of these two phones, I will list the major differences here:
1. Screen- The SGS2 will offers a screen resolution of 480 x 800 pixels at 4.3 inches, while the SGS3 will offer 720 x 1280 pixels at 4.8 inches
2. CPU- The SGS2 offers a Dual-core 1.2 GHz CPU, while the SGS3 offers a Dual-core 1.5 GHz CPU
3. Internal Memory- The SGS2 offers 1 GB of internal system memory, while the SGS3 offers 2 GB
The SGS3 should also support Sprint's LTE network, where as the SGS2 (Samsung Galaxy S II Epic 4G Touch) will not.
