With a new 5.0 operating system due to make its roll-out later this year, there is word that a 4.2 operating system for the 8700 and 7130 models is available at RIM. The question is will carriers provide this upgrade.

Within the concept of ever-increasing redundancy, the new models are more attractive if the old models can’t do the same things or have the same functions. Oh, you want YouTube videos for the BlackBerry? Then you might want to upgrade to the new model. Your Berry doesn’t have GPS? Lame. So why make your older BlackBerries more efficient when you can sell your customers and bigger better and shinier new one?

We’ll keep you updated on new systems if they become available.
