Yahoo! is making lots of changes to most of it’s products amidst startup acquisitions as well. The company made significant redesign of Yahoo! Mail earlier this week. Yahoo (YHOO) has again announced that it has completely redesigned it’s Flickr iPhone app. Now once you take a shot with the Flickr iPhone app, there‚Äôs a built-in editor to quickly correct, crop, or enhance it with one of the new filters.

The new Flickr now includes filters and editing features similar to what users are used to on Instagram and the new Twitter filters. Twitter announced on Monday that it would offer its own filters and editing services for pictures within its mobile apps after Facebook’s Instagram blocked the ability for users to display photos on Twitter.

The user interface is completely redesigned. The photo sharing app also features 16 unique camera filters, full Groups capabilities, the ability to explore photos based on location and a new simple Flickr sign-up and registration process from directly within the app. You can also share your filtered images via Facebook, Twitter, Tumblr or email.

New Flickr iPhone app

Just like our Flickr site, you can upload unlimited photos from your camera roll, add your photos to groups and sets, add a venue from Foursquare and tag people.

The new Explore tab allows you to see the most interesting photos uploaded every day. You can see the photos that have been captured around you. And the new Contacts view also makes it easy to discover photos from your friends or favorite photographers.

The redesigned Flickr app is part of Marissa Mayer’s strategies to reinvent Yahoo! since taking over as the new CEO.
Mayer, 37, has said that enhancing Yahoo’s mobile offerings is her “top priority” since arriving to lead the company in June from competitor Google.
