Iphone 11. iPhone 4 wallpapers are now available that will show off the iPhone 4 and its Retina Display Support at its absolute best. These are the sort of wallpapers I would go for but be warned the choice is vast! Generally expect to pay a little for the apps but certainly no more than 59 pence. These apps will have a nominal selection of iPhone 4 wallpapers immediately available for use but as a rule a quick download is the norm. The apps generally set the wallpapers in different sub sections so it is well worth having a mental picture of what you are looking for and sticking to that idea that is unless you have plenty of spare time on your hands.
