While no wireless service provider has picked up this hot little handset, the Nokia N91 – touted as an iPod killer by some – is now available for order through the Nokia USA Online Store. Its features are many, its design is beautiful, and as a result, it has a price tag to match.

Intended as a device to provide high-fidelity music, the Nokia N91 comes packed with a 4GB hard drive to store all your MP3, M4A, WMA, AAC, AAC+ and eAAC+ files. In addition to the dedicated music keys and easy PC synchronization, this “mobile jukebox” comes with a fairly standard 3.5mm stereo headset jack. There is also a 2 megapixel camera on board, as well as push email support, internet browsing, and even love for RSS feeds (we know you can’t live without Mobile Magazine on the go, right?).

All that said, Nokia isn’t leaving your basic telephony and connectivity things behind. Hop onto the Wi-Fi hotspots with the WLAN support, make use of your rockin’ new headset with the Bluetooth wireless technology, and get your 3G groove on with WCDMA. And yes, of course it does the basic GSM/EDGE thing too.

The Nokia N91 is available now for $599.
