Chat Crash(Vote 1)

lets put it like this tracy it crashes for every device

Members in my alliance found that the pms are causing this so we have cut off all pms within our alliance so no pm 

every time i try to chat on my iPhone 3Gs it crashes all the time but if i delete then re-install it will go to chat but when i exit the chat then try to go back it crashes its ok though because i have a iTouch 2G witch it dosent crash on but i would like it fixed for my iphone witch i use most
