I have said that multi tasking, changing themes, simply notification system, easy access to control etc were not a big deal..........I WAS WRONG!
You were right!
I have a 3G iPhone and now jailbroken......wow! unleash the power of CONTROL!!!!
I have everything OS 4.0 has except a unified mailbox. Unless there's some incredible hardware upgrade, why would I spend the money? I can do EVERYTHING on my 3G now!!!
Great Notification system on my locked screen. Quick reply FROM my locked screen. Immediate access to control, 3G, Wifi, bluetooth etc with a gesture and multi-task (everything or apps of my choosing).
Everyone SHOULD Jailbreak their phone!!!!! Unleash the iPhone power.
