iPhoneSlide is a free service for instantly uploading your iPhone photos to Twitter, Flickr, Facebook, Typepad, Blogger, Wordpress and more. You do not have to register to use iPhoneSlide.

To get started, just email a photo from your iPhone to post@iphoneslide.com. You can enter a subject in the email which will be used as its title or status message. You will get an email confirmation back to select which services you want to upload your photo to.

The email confirmation contains a URL which you open in your browser. From here you choose the services you want to upload your photo to. The defaults are Twitter, Flickr, and WordPress. This page contains a link to add services, which allows you to add more upload destinations such as Facebook, Blogger, and TypePad. The first time you perform an upload to any of these services there is a bit of setup work and confirmation steps involved. Future uploads should be bit less involved.

For those worried about privacy, the company states that “Your username, passwords or any information your provide will never be used or sold to third parties”. As always use at your own risk. Try with TestiPhone
