We've seen a lot of new sites popping up designed specifically for the iPhone. What's more, many existing sites have designed iPhone-sized interfaces to make the iPhone user experience of their services more welcoming. The latest of these offerings, iRovr, is a full fledged social network designed specifically for the iPhone.
iRovr offers blogging, photo sharing, video sharing, bookmarking and user profiles - but all sized to fit the iPhone's screen. Media sharing is accomplished through POP email aliases.
Sites such as Digg and Del.icio.us have already offered iPhone an iPhone sized interface. However, the largest sites in social networking land - such as MySpace, Facebook, and Orkut - have not.
