There has been questions of what Blackberries on the market will get the up and coming Blackberry OS 5 update. Over at the Blackberry Technical Solution Center they released this document that states the devices that will be supported. Looks like devices that have more than 64MB of memory will be able to upgrade to the new OS coming out. So all of you guys with the 8300/8310/8320 will have to stick it out with the older OS, but there are plenty of new devices coming out that I’m sure will have OS 5 loaded onto it.
