So can I still put music on my iPhone 4 now that its jailbroken?
+1... the only thing you'll need to be careful w/ regarding iTunes is NOT updating when it prompts that a software update is available. Be sure that a Jailbreak of your preference is available (Tethered or Untethered) for that software version first, because updating will un-Jailbreak your device.A jailbroken iPhone works exactly the same as a stock iPhone...
