i have a jailbroken iPhone 3G with 4.0 (enabled multitasking)
problem is, it gets reallyyyyyy slow and usually only has 4mb of free RAM. it even skips when i'm doing something as simple as playing music while web browsing. it crashes and freezes a couple times an hour.
i rarely use the features of 4.0 and it's not worth the HUGE drop in performance to me. i'm getting an iPhone 4 next month so i won't have to deal with this problem much longer, but until then, i want to downgrade the 3G to 3.1.2
i don't see any buttons on itunes to downgrade it.
please help.
THANKS!
