The Nokia N900 has a secret FM radio receiver which is not on the official specs. Although it's hidden by default, you can unlock it by installing a special unofficial application, as shown in the video below. The video also briefly demonstrates the N900's FM transmitter which lets you listen to music files and internet stations on any nearby FM radio (which is quite handy in a car).

There have been several firmware updates since the N900 was released, and more are on the way. The video below is intended for beginners who need a little help with updating their device. You don't need a PC, the update can be done entirely on the phone itself.

There are two main methods for installing applications and games on the N900: through the free software catalogue built into the App Manager, and through Nokia's own Ovi Store application shop. Both of these methods are demonstrated in the video below, which is intended for beginners.

The word "widget" has been used in so many contexts in computing and elsewhere, it can sometimes be unclear what exactly it means. On the N900, widgets are simple applications you can add to the desktop, and the video below goes through all the basics.

In our latest AAS podcast, Insight 105, Steve and Ewan discuss the news and announcements from Barcelona, including the Sony Ericsson Vivaz pro, Symbian^3, Skype for 5th Edition, Nokia's Maemo/Moblin deal, Windows Phone 7 Series Pocket Pro Mobile (or something like that) and anything else which we thought of interest and relevance.

Rafe and Ewan McLeod are hard at work bouncing around Barcelona, and they caught up with a number of companies at the MWC MobileFocus evening. One of those companies, Swype, promises a “faster and more efficient way of entering text on a touchscreen device”, as Rafe finds out in this Video Report with Mike McSherry and gets his hands on an alternative input system.

Nokia and Intel took to the podium at the Mobile World Congress event in Barcelona today to announce that their respective Linux projects, Maemo and Moblin respectively, will be rolled together to create a new Operating System to be called Meego.

With the mobile industry gathered in Barcelona, MWC Day 1 is underway. In this post, we'll be bringing you live coverage from Nokia's event. The event kicks off at 10:30am GMT and we'll be covering both the press conferences and some of the follow up events and interviews.

The N900's media player application has an internet radio section which contains lots of radio station bookmarks, but no obvious way of adding more. The video below gives an example of how to add more stations to the list, and how to remove stations too.

The N900 has instant messaging and VOIP totally integrated into the interface, but officially it only supports this integration with Skype, Google Talk, Jabber/Facebook and Ovi. Unofficially though, more services including MSN / Live, AIM, Yahoo Messenger, ICQ, QQ and others can also be used in an integrated way. The video below shows exactly how to activate them, it only takes a minute and you only have to do it once.
