I just got the 8300 series and wanted to upgrade to the most recent blackberry "thing"

I didn't realize each update version is limited to specific phone models...

is there a way to get the latest software on my blackberry 8300?? what's causing me to be inable to download the most recent software??

Blackberry's are pretty confusing... usually I just plug my iphone in and its done... You dont even want to know how long it took me to update just the BBMessenger!!


please help me =/

Re: CURVE 8300 UPGRADE TO 5.0??

Hi and Welcome to the Forums!


Take a look at this sticky thread in this forum:


Xandrex is very kind to maintain a list of most recent OS levels from various carriers for many BB models. Find yours. Find the carrier with the OS level you want. Go to their download page via this portal:

Download the package and use these instructions to install it to your BB:

If you chose an OS package from a carrier other than your own, be sure to insert, between steps 1 and 2, the deletion, on your PC, of a file named VENDOR.XML


Good luck!

AFAIK, OS 5.0 isn't available for the 8300, only for the 8330.
