My friend at work has an iPhone 4(s) jailbroken and wow.. I never looked at one... the options.. the customization capabilities are amazing! He was able to turn on/off bluetooth with literally 2 clicks... which is very convenient instead of the Settings>general>bluetooth>on/off... The only complaint he had was that the battery seems to be drained easier... I wonder why Apple doesn't allow such customization or edits their own theme to make it more user "friendly" ?
