Way back in May, there were rumours that Palm was prepping two new devices - codenamed the Zeppelin and the Skywriter.

Well we don't know if this latest leak could actually be one of these devices but it definitely seems that Palm has been busy and a new launch may be on the cards.

An ad has managed to leak onto the web and it has been picked up by Palm Addicts.

It looks like could be for Palm's update to the Centro, the Centro2 smartphone.

The whisperings are that it will have a touchscreen or slide-out pad (because there's no keyboard shown in the pic) and the blog is saying it will run Windows Mobile.

We will keep you posted.
