Pretty much just that, I try to update to 4, on my iPhone 3.1.3 3GS leads to it extracting something, then erroring telling me that there's not enough space to update. There's 229MB free on / and over 2 gigs on /var. If this has to do with system space, how would I reduce some of it before updating? The phone is jailbroken (I already backed up my cydia apps Please Register or Log in to view images and I just wanna update to 4 for the new features, then JailbreakMe. So, what do i do? Ive already done an itunes sync 4 times, and DONT feel like restoring.
