There are many photo sharing sites out there but this one is different. Natuba is a photo sharing site, which is meant exclusively for the iPhone users. Users can click photos from there iPhone and share it with like minded iPhone photographers. Users are given a special email address to which they can mail their iPhone clicked snaps and they will be added to this website. You can add some comments to your pics and they will be inserted into the public gallery, you can have your photos mailed to your profile on Natuba and also have random pics, clicked from you iPhone, to be displayed on your profile. Many photo sharing websites have the mobile upload facility but this one only iPhone, they major turn-off being this website does not support any other mobile phones. May be this website will have more users once the iPhone penetration increases, but I feel that this site should support uploads from other devices also, if it wants to stay up and ahead of other photo sharing websites like Picasa and Flickr
