After running IOS4 on my 3G with multitasking and homescreen wallpaper enabled, I've decided to restore and leave them disabled. For me speed is more important than these functions. However, I will be using Winterboard when it's stable enough to use (it may be already, I don't know). What I want to know is, will the user wallpaper function in Winterboard take up more or less resources than enabling homscreen wallpapers as part of the Redsn0w jailbreak? Essentially they provide the same function, but obviously if one is more efficient than the other then I'd prefer to use that.
