Amid all the new handset news and updated apps coming out of Nokia World this week, Nokia has also announced that it's completed its plan to acquire Symbian.

If you remember back in June Nokia announced its plans to buy up the remaining shares of Symbian that it didn't own in order to create the Symbian Foundation. The idea behind the Symbian Foundation is to establish Symbian as an open source, royalty free OS available to all foundation members.

At the time, Nokia only owned around half of Symbian, with the rest split between Sony Ericsson, Ericsson, Panasonic, Siemens and Samsung. The good news is that its offer for the balance has been accepted, which means it now owns Symbian outright.

This means it can now give all Symbian's assets to the foundation so it can become an open source mobile OS. Nokia will also be taking on all Symbian employees, who will join the company on 1 February.
