Back in May, we heard a whisper that RIM was planning on releasing a 10-inch BlackBerry Playbook, with a possible launch as soon as the end of 2011. On the face of it, it seemed like a logical step, but it's no longer a step the company is making, if new rumours are to be believed.According to the N4BB site, the entire development programme for the larger PlayBook has been cancelled. Why? Because the company is working on a phone using the same operating system used on the tablet – QNX. Not just any smartphone either, it's being called a 'superphone'. Wow indeed.How super? Well, that same site has some initial specification details, which include a single-core 1.2GHz processor (same as that used in the Bold 9900), which might be upgraded to dual-core if battery issues can be attended to, a 900+ screen resolution and a 4.3-inch touch-screen. So not as super as we would have hoped, but potentially an impressive smartphone, that's for sure. As yet, there isn't a name for it, or indeed a release date. But there's a track record for BlackBerry image leaks well in advance of launch, so just sit tight for a few weeks.On the PlayBook front, the company is now devoting resources to producing a 4G PlayBook, intended for launch in October in the US. Not scheduled for here obviously, as we don't have the network to support it. But there's always a chance of a 3G model being thrown our way around the same time. We'll keep you posted.
