Evening all... My iphone 4 is not as smooth running as my friends non jailbroken phone. His is older than mine and when I for example switch apps using the multitasking menu apps dont switch smoothly they almost stutter and flicker into the chosen app whereas my friends is very smooth no stuttering at all. He even has more apps open then me, I only have email and settings and facebook running... not sure if my phone is faulty or if its the jail break. I only have cydia and auto3g installed no other apps from the jailbreak. Im on 4.1 operating system. Cant remember what it was like before hand you see. Everything else works ok. Hope someone can advise me what theres is like.
