New tweak with a name STATUS TWEAK has been released in CYDIA which helps the user to customize the status bar. This tweak is only compatible with IOS 4+. Items in the status bar can be adjusted in any order (Together, Space them apart, disable, etc).
Status Tweak also includes some modification for specific bar items such as disabling “AM/PM” & replacing carrier name with current date.
It is a very nice & user friendly tweak & is available for free in CYDIA for all jailbroken iPhones.
