Nokia have added a new countdown on its website which will expire tomorrow at 2PM BST.

The countdown promises that "It's time to try something new" as well as adding "Something new to Symbian". Apparently for a while Nokia messed up because the banner was called Symbian Belle teaser, which is a huge hint that they will be announcing the Symbian Belle operating system update.

Symbian Belle is the successor to Symbian Anna which recently launched. It's expected to bring a number of improvements including drop-down notifications, a task-switcher and a new app store.

Further rumours suggest Nokia will be unveiling three new Symbian Belle handsets including the Nokia Cindy (Nokia 600), Zeta (Nokia 700) and the Helen (Nokia 701). Why Nokia has gone so mad on girls names we don't know, but its better than a long meaningless name like Nokia N900 Navigator.

The new smartphones are expected to have high-end specifications , but we don't have any concrete information. We'll just have to wait till tommorow but as soon as hear anything you'll be the first to know.
