Hi, this is my first posts but I've reading this forum for a lot. I need help. I have iphone 3gs 3.1.2 and gpsphone 6.6.7 and this my problem, happen with all games. When I start a game everything is perfect but just for only 1 minute, then the game starts to have problems,the game starts to have a jerk (the sound flows ok) but is the image/game... sarts like jark, hags for miliseconds, slows but for milisecons (im' sorry I dont' know the word in english) is playable but just RPG, beacuse other games is difficult. What is my problem, I saw a video in youtube the gpsphone at 150 fps for 3gs, and I can run my games ok at 60 ?? here are pictures Everything is fine... and then ... starts.. What can I do? thanks.
