iFans has reorganized its screenshot and wallpaper threads within the discussion forums to better suit the increasing number of iOS devices that have been released in the last few years. For starters, there is a designated iOS screenshots thread for all iPhone, iPad or iPod touch screen captures. In this thread, feel free to post your home screen, lock screen or other screenshots pertaining to iOS software itself, regardless of which device you have.
As for posting wallpapers, there are now official threads to do so based on the device you have. If you have a new iPhone 5 or fifth-generation iPod touch, post your 4-inch wallpapers in the official thread for those two devices. If your device is an iPhone 4S, fourth-generation iPod touch or older, try posting in the older iPhone wallpapers thread or older iPod touch wallpapers thread instead. Last, there are two threads for iPad wallpapers and iPad mini wallpapers.
