Recently, I've been contacted by Luca di Cesare, the creator of iWikiPhone. In a nutshell, iWikiPhone is a social network for iPhone users. At iWikiPhone everyone is able to talk about iPhone, post application reviews, share experience, insert videos and so on. iWikiPhone is built around true Wiki spirit.
If you want to become more productive with your iPhone and enjoy your wonder device in even better and richer ways, I highly recommend using iWikiPhone. The service is free and open to everyone.
Finally, I'd like to note that that Luca Di Cesare is an Electronic Engineer and online sales and management consultant. He has been awarded third place among the best start-up participants at the TechGarage2009 Users Choice Awards.
