Hot off the presses, the Storm 9520 has finally caught up with the rest of the devices getting into the .7xx OS builds. This is an official OS for Docomo Pacific, and can be downloaded straight from Blackberry (link below).
Please remember that if you decided to load this OS and Domoco Pacific is not your carrier you must delete the vendor.xml file prior to install. Also make sure that you have a current backup file before begining installation.
NOTE: While this is an official RIM release, Nerdberry.net will not be held responsible for any damages caused by loading this on your device.
Any Storm 9520 users out there let us know how this OS is by jumping over to the Forums and report any findings, bugs, or whatever.
