Does Anyone Know How To Change The Battery Icon Back To Default?

Im using summerboard and i changed my icon but i hate what i changed it to, i cant seem to find it to uninstall it and i want the default

i posted a post in the help section but no replys..

sorry to ask again!!

hey yeah it does, i totally uninstalled it and restated my phone and its still there..

can you advise me, can i restore my phone and not have to unlock it again?

like, i brought it from eBay already jailbroken, 1.1.4 but i dont know how to do it myself, is there a way of resetting the iphone back to kinda normal lol without having to unlock it again totally?

In terms of getting my battery icon back (

It seems petty but its SO annoying and looks so ugly (

thanks for your help!!
