In addition to device info, images of the BlackBerry London also leaked via The Verge. They disagree on the timeframe, saying that the London will hit in June, or late Q2 2012.
Spec-wise, the information is that it will sport one of TI's ubiquitous OMAP dual-core CPUs, running at 1.5GHz, 1GB of RAM, 16GB of internal storage, a 2MP front-facing camera, and an 8MP rear-facing camera. We have to say that by Q3 2012, or even late Q2 2012, these specs will be severely outdated.
While late Q2 2012 / Q3 2012 seems (and is) a long ways off, RIM still hasn't gotten BBM and BES working on BBX, and that has reportedly proven to be a challenge. The question is, will RIM even be relevant by either of those dates?
