There are a couple of apps available in the app store that specialize in collecting/sharing iPhone wallpapers. I got one called iWallpapers HD. It's free. It's ok. Big selection but not in the area of sports. If anybody has any idea of a spot where I can locate a selection of SPORTS themed Retina wallpapers I'm sure some other members as well as myself would appreciate it.
whats the best way to get these on the phone without loosing the hi res
Or you could browse to the site on Safari on the iPhone and copy that way as well. I find this works the best without having to save everything to my computer.
I just found the iWallpapers HD app and there are some really nice ones there. I had another app, can't remember the name of it, and they had some cool pics but not hi res ones. It's a shame not to get hi res to take advantage of the beautiful display on this phone!
