how do i update my n900 with this new update ... thanks in advance
The SDK is used on a PC to test and compile (and most things developing) for Maemo 5. It is NOT for the N900. Or for end-users in general. The corresponding update for the N900 (PR1.2) should be coming soon, but not within the week (or next week) as most developers need to have time to prepare for the Qt 4.6 changeover (as far as i know). Correct me if I'm wrong, please.
