Anyone who uses the Flickr photo sharing website will already be aware that the iPhone is one of the most popular cameras used in the 3000 photos uploaded each and every second. Well using Flickr on your iPhone has just become even easier in the form of a dedicated (official) flickr app.
The official application is completely free and allows you to take photos on your phone, upload to the Flickr website. You can search Flickr, easily add comments. Personally I find it an easier way of watching the activity on your photostream with a full list with comment and favourited count. This is particularly useful if your photos (unlike mine) receive a lot of comments or favourites.
As well as supporting the ability to take photos directly from the iPhone camera it also supports video uploads on the iPhone 3Gs. Flickr introduced the ability to upload video a number of months ago but to me Flickr is for photos and Vimeo for video.
The interface is simple and easy to use, it offers the ability to comment, move to the next and previous photos as well as email a link to a particular photo to a friend.
Tags are also well supported on the iPhone app and clicking on a tag name displays a list of the relevant photos.
With Flickery for the desktop and now a brilliant iPhone client there is no excuse to have an up to date well managed photostream. The official Flickr iPhone application is available now via the Apple iTunes Apps store and is free.
The Flickr for Windows Phone 7 app is due out today at some point as well:

This app is so much better than Instagram in so many ways. It came out as a web page at first, about 5 years before Instagram was famous.
