Light a bright idea for your iPhone 4 (Appolicious)

Appolicious - LED Light for iPhone 4 Free is a useful, must-have utility that turns your iPhone 4 into a working flashlight; it has become a bit of a cash cow for its creator as well. Developer Jason Ting revealed that his 9,000-download launch day made him almost $1,400 in ad revenue through Apple’s sanctioned iAds program. It’s unlikely that Ting will sustain these returns as downloads slow and initial use tapers, however his experience does bode well for other developers considering iAds.
