Okay has anybody else upgraded to OS4 and what kind of iPhone do you have? Have you experienced slowed down performance or anything? I really think Apple should have warned 3G and 3GS users that they could experience performance issues because I have been seriously pissed off with my phone since I upgraded it. It became slow as fuck, to the point where I wanted to throw it at the wall.. and all you get out of it is a zoom on the camera (which can be attained by downloading Gorilla Cam for free anyway) and a folder system which really is not worth the decrease in performance. Anyway I tried to downgrade once (which i dont think is strictly legal) but my old computer was fucked and couldn't finish the job properly.. But now that I have a laptop I managed to get it working properly and I've managed to downgrade back to OS 3.1.3 and I no longer feel the need to dismember my phone (if it had members that is). I seriously feel so much better, it's unbelievable.
