SP Photo Cal Lite
iOS iPhone Photography
The easy way to create a calendar for your iPhone/iPod Touch wallpaper, using pictures from the Picture Library
Using touches, picture and calendar could be moved and scaled individually before saving the final art.
When the phone is locked, the "Clock" and "Unlock Slide" are located on the top and bottom sides of the screen hiding part of the Wallpaper. "SP Photo Cal" has semitransparent bars on the top and bottom sides to simulate the "Clock" and "Unlock" areas, helping you to locate the calendar on the most viewable section.
The saved image is stored on "Saved Photos" / "Camera Roll". From here, you could follow the regular process to set a photo as wallpaper.
Lite version creates the calendar based on current date
Full version allows you to select month/year (current date is default when application starts)
Full version also allows different font/shadow colors.
