Over-the-air PR 1.3 firmware update for Nokia N900 is now out in the Philippines!
I just received it on my device.
If you haven't received the notification on your Nokia N900, just go to App Manager, click on Updates and look for the Maemo update.
As it turned out, PR 1.3 won't be bringing the earlier reported Nokia N900 MeeGo dual boot option. However, as mentioned in Maemo.org, PR 1.3 is supposed to aid developers dual boot their devices into MeeGo and this would be the main draw come MeeGo Conference happening in November. Also, developers would be happy to know that PR 1.3 aligns the Qt application and UI framework with the planned version for MeeGo 1.1 platfrom (Qt 4.7). So in effect, even without an actual MeeGo 1.1 handset, developers can start building apps for it using their updated Nokia N900.
Nokia N900 PR 1.3 firmware update, which weighs around 85MB OTA, brings stability improvements, several bug fixes, and support for Ovi Suite.
I'm updating my phone now. I'll let you know what's new once it's done.
