Hello, I did a master reset on my iphone 3G in order to get the files and settings of the old user off but the phone refused to come up later. it just shows the apple logo on a black background and stays there for hours. I could av used iTunes but i don't have internet so fast and consistent to download over 300mb wiithout break and which may not take even days to complete so i went online to check for alternatives. Now I av downloaded using a download manager, the ipsw files necessary but i get the error message in iTunes that firnware is not compatible. please what do I do cos i can even use the phone for anything and this is the 4th day? Thanks to all the geniuses in this forum.
