so i have updated, and jailbroken my iPhone no problem. I did DFU-update as to avoid reboot cycle. so now, my iPhone is running soooo slow that my songs skip. there is nothing physically wrong with the device so its not a bad HD or whatever. this ONLY happened right after i updated. I jailbroke it on my mac, using redsn0w but when i did it, i clicked 'add personal background (something like that)" and '' Enable backgrounding'' i havnt gotten the backgrounding of apps to work, but i have reason to say that that is the reason for my troubles. SO! my general question is does it make a difference? right now i am going to try and do it over, but without the background apps and see what happens. But i want to know if this has happened to anyone else, and if what i am going to do may solve it. +++ Its so slow, that i cant text properly, and music takes forever to load so its pretty noticeable.
