The Nokia N91 is a mobile phone that was released to the public in April of 2006. It is one of the Nokia Nseries mobile phones Nokia are launching in an attempt to place them firmly at the top of the mobile phone market. It features a 2-megapixel camera and a 4GB (8GB in the "new" 2006 version) hard disk to store up to 3,000 songs encoded in either AAC, AAC+, eAAC+, MP3, mp3PRO, WAV, MIDI, or Microsoft's WMA format. It also features 3G and wi-fi technology. The phone features a 176 x 208 color display and dedicated music functionality buttons (XpressMusic) that slide down to reveal traditional mobile phone keys. Battery life when solely playing music has been estimated at 12 hours.
The phone features a new version of the Symbian Series 60 Operating System. It was the first phone with this version (Symbian version 9.1, Series 60 version 3.0). The new version is needed for the support of a mechanical hard disk. In the past, the version of the Symbian operating system has been a good indicator of cpu speed.
In designing this product, Nokia hopes that it will help them outsell Apple Inc's iPod and become the biggest MP3 and digital camera maker.
In the adverts for this phone, it clearly stated that, because of its 3.5 mm plug input, Nokia recommends quality headphones made from Bose and Sennheiser.
N91 also comes standard with a full Web browser
There have been a few problems with the N91, namely connecting the phone to an Apple Computer Mac OS X compatible computer. This will often cause the phone to crash as the two units are disconnected and music files are often not recognised despite being loaded into the phones hard drive. Also depending upon which firmware you have, when you install a new theme, it will reset itself back to the default theme. This can be fixed though, by updating to the latest firmware which can now be done by the user themself.
