Ive used some of these myself with great success. You really must take care here though and only use a reputable download site. iPhone wallpaper can be freely and legally download without problem from a trustworthy source but pick the wrong site and you could end up in trouble with the possibility of viruses and trojans infecting your computer or your iPhone.
