Kick-ass mobile social network and IM aggregator, Xumii, has just released a new version of their app.

Updates include:

• Check up on your recent chats - The newest chats now have their own tab in the Friend Chat section–check out “Recent.”
• More organized contact lists - Have tons of buddies? Now there are tabs for each social network so that your Facebook or AOL buddies have their own lists.
• Faster start-up - We don’t want to keep you waiting.
• In-Application Sign-up - New users can sign up and add identities from Xumii on their phone.
• Uploading larger images- You can upload photographs larger than 250K from your phone into your facebook, imeem and myspace social networking photo albums.

The fight is still on to see who will dominate the mobile social network/IM space, but the Xumii team are doing their best to maintain their position as one of the favourites.
