you should downgrade your iTunes 7.7 to iTunes 7.5 first(at first unistall iTunes 7.7 and restart your PC)before using iTunes7.5 you should goto(in Windows) My Documents>My Music and rename "iTunes" to "iTunes backup" then run iTunes7.5 (it`s nesscery for your 7.5 to run) ok,now put your iPhone to DFU mode(I hope you know how to put it!!!) and in iTunes shift+Restore ,choose firmware 1.1.4 (if you don`t run your DFU Mode correctly iTunes will give Error 1011,1013,1015,6,20,...) at last your iPhone will go to Recovery mode , now take it out from Recovery position with iLiberty+ 1.3.0.113
now your iPhone is up with firmware 1.1.4 but maybe your Phone is jail,now use this program (http://rapidshare.com/files/11940767...04.05.04_G.zip) for downgrade your baseband to 04.03.13(don`t forget choose downgrade baseband and debug boot)
