A minor firmware version 1.2009.44-1 has been released for the N900, that should set thing up and make way for the upcoming major update build 51 (PR-1.1).
The software is will be available as an over-the-air update (18.5Mb) or via the Nokia Software Update on the PC (160Mb+). N900 users connected to the Internet should receive a notification in the device’s Status Area that a software update of Maemo 5 is available. Alternatively you can go straight to the App. manager and go to “Update”, there you should see an update called ‘Maemo 5.”
We have yet to see a change log, but visible changes include:
-An updated Application Manager with icons for the various categories,
-New app catalogs (including OVI),
-App. Manager stays in the background during and after install
-Enabled OVI store via browser
-Red Pill Mode removed
-Prepares the Nokia N900 for the Ovi Store app (store opening shortly)
-OVI Store accessible via Browser
If that wasn’t enough, Nokia also pushed updates for several pre-installed apps, including the Facebook widget, Bounce, Documents To Go, etc.
What changes did you notice with the new N900 update?
Minor firmware 1.2009.44.1 (PR1.0.1) Now Available for the N900

Nothing beyond what you’ve mentioned. Have had it for 12-hours and haven’t noticed anything other than the inconvenience of removing red pill.
The good news is we have all been waiting for those very important icons in the app manager, updates to the installer apps you mentioned (not the apps, but the installer apps :-/ ), and most importantly, the ovi store.
I’m not holding my breath on the larger update. Been seeing too many WONTFIXes on maemo and the weird, non-customer centric approach in maemo’s and nokia’s bugs/forums to expect much. Hopefully they at least get the bluetooth problems squared away so I don’t have to carry a backup so I can talk and drive.
When you install an app and getting back to the list with apps, you stay where you are and dont go all the way back up to the top of the list. this way you can scroll further and dont have to find the same spot again. (sorry for my bad english)
I’m having a problem connecting even before the firmware update. I can access voip, skype, email, browser, some repositories. But do not access services as the official repositories Nokia, Ovi, MaStory (wordpress) and Webtext (SMS voip).
My firmware is 2.2009.51-1.002 I updated the NSU (USB cable), because the N900 could not connect via wifi (time out).
Any suggestions on how to fix it? Thank you!
