More details on the upcoming Nokia Carla release came in. The platform previously known as Symbian will get its next update in Q3 2012, when the first smartphones running Nokia Carla will hit the shelves.

According to the latest rumors, second-gen Belle smartphone, including Nokia 603, 700 and 701 will start shipping with the new version of their OS first. Later on, the rest of the Belle-running smartphones in the Nokia portfolio will get Carla as an update. Scheduled for Q4, the update should cover N8,C7,E7,X7,E6,C6-01.

Despite what previous rumors were saying, Carla will be distributed to all smartphones currently on Belle. However, those that lack NFC capabilities and 1GHz processors will get a trimmed down version of the update to avoid performance hiccups.

The Upcoming Nokia OS (previously known as Symbian) codenamed "Carla", shows up in screenshot form. The leaked screenshots does not show much but give us an idea about what Nokia is improving on the Mobile OS.

First, there is the new on-screen QWERTY keybord, which seems to have been inspired by its Windows Phone cousin. The Nokia Browser has also been updated to a new version, which features some new UI improvements.

But the most noticeable change comes from the lock screen. Gone is the classic Unlock Button, and replacing it is a Swipe to unlock method. The user interface of the Music player also sees some improvements in the form of a refreshed UI, as does the Options screen, which borrows the looks of the Meego Harmattan UI.

Selected Models (Nokia 700, 701, 603 and the Nokia 808) of Nokia devices will get this Update on Q3,2012.

After the drop in Nokia's Symbian devices last quarter, Nokia Italy has officially revealed that Symbian "Carla" the 3rd version update of Symbian after "Anna" and "Belle" is CANCELLED!

Nokia fans still waiting for an official announcement from Nokia main Department in Finland, but if this really true, this will mean that Symbian is fading away quicker than expected. We don't know whether there's a direct connection between Symbian sales and the update plans, but in either case, news is that the last update to the burning platform will be Nokia Belle Feature Pack 2.

A couple of Days ago, some reports from Nokia Italy claimed that the Carla update is canceled. Today, Nokia confirm that "Nokia Carla" Update is not canceled but may be a bit delayed.

According to our source at Nokia, the Carla update, or Belle FP1 as it will be known as, is not cancelled and will start rolling out shortly. The first phone to run on this update will be the upcoming Nokia 808 PureView and soon some of the existing Nokia devices, which includes the Nokia 700, 701 and 603, will be updated to Belle FP1
