There is a site dedicated to iPhone/iPad/iPod (link not give that would not PR). There are prizes for the contest: iPod touch 4G, iPod shuffle 4G, speakers for iPhone/iPod.
Puzzling over the idea of the competition that would be both interesting for all readers of the site and, at the same time, was not simple and banal.
The main condition to take part in the contest can be anyone (CIS).
Writing reviews of software iPhone/iPad (who is better) is not suitable.
Grateful for any ideas.
