So someone told me i could get battery percentage on my ipod touch 4 using ibackupbot, so i watched a tutorial, did everything it said, typed in the correct lines in the backup, and everything went fine. Well, after a couple of tries, but yeah now i have the battery percenateg working, but it has really messed up my ipod, i'm currently in England but the restore from ibackupbot changed the app store currency and itunes currency to dollars instead of pounds, so i can't purchase anything, how do i change my currency back without deleting my battery percentage? please help!

tl;dr: ibackupbot changed my currency and settings, help

p.s Does anyone know anything else you can add with ibackupbot, like siri or something? thanks.
