RIM looks likely to announce new handsets running the latest version of the BlackBerry OS tomorrow, including the upgraded version of the BlackBerry Torch.

RIM has invited press to a 'Media Event' on 3 August, which raised speculation over whether it would be anything from a longer demo of the new BlackBerry Messenger to new phones being released.

Well, it looks like it will be that and more if recent rumours and our sources are to be believed - the BlackBerry Torch 2 looks nailed on for a launch, and could come as the BlackBerry Torch 9850 or the BlackBerry Torch 9810, depending on which internet rumour you believe.

What's occurin'?

Details on this one are sketchy, but another phone that could make an appearance is a touchscreen version of the popular Curve 8520 - although whether this is just internet rumour completing the circle is unclear.

And finally we're hearing word that a third phone could be turning up: the BlackBerry Monza - AKA the BlackBerry Torch 9860 - which could be the full touchscreen model we've tipped to launch so often.

But what is certain is anything that does launch will be running BB OS 7 - co-CEO Jim Balsillie pledged seven new devices in the coming months and needs launches to prove to be true.
