With the launch of the BlackBerry Bold 9700 on AT&T for business customers RIM has finally posted the OS download for the device. AT&T is lagging behind in OS versions at this point, considering Rogers launched with OS 5.0.0.321 and T-Mobile launched with OS 5.0.0.344 and we already know RIM is well ahead of that as well with current OS sitting at 5.0.0.351 or higher. In any event, if you for some reason feel the need to reload your OS on your brand new AT&T 9700 the files are there for you to do so.
