I have a jailbroken iPhone4, when i go to bed.. ill charge it, i turn my laptop off when i go to sleep unplug my iPhone which is now at 100%.. i wake up and my iPhone is on 75% or less.. wtf? I don't have winterboard installed. I have activator, bitesms, cyntact, emoji, five icon dock, iconclasm, fiveicondock, ifile, infinifolders, libdisplaystack, lib weather, make it mine, music controls, remove recents, retinawallpapers hd, sbsettings, snaptap, wifisync and 3g unrestrictor. I am on 4.0.1, i tried to restore it using 4.0.1 firmware i downloaded and it says iPhone unable to restore due to firmware being for inappropriate build or something along those lines. I went for a day out the other week, got 5hrs 30 mins useage with music playback and some internet browsing on 3g, few txts and calls, that can't be right can it? Help pleaseee!
