I recently switched from Sprint to Tmobile, both carriers version of the SGS2, and noticed a startling difference in graphics performance between the two versions, most easily witnessed whilst playing the game Doodle Jump. Mind you this is not a graphics intense game, but the Tmo version of this phone just cannot handle it. My gf has the same exact phone and gets the same results. Is the graphics capabilities with the snapdragon processors that much worse vs the original processors used in all other variants of the SGS2??
