BARCELONA, Spain--At Mobile World Congress in Barcelona, Nokia's design chief, Marko Ahtisaari, introduced a bundle of new Nokia phones, starting with the Nokia 301, a classic 3G cell phone with some software tricks.

Ahtisaari holds the 301 aloft. It comes in a range of colors, including yellow, white, cyan, and black.

Nokia's Lumia 520 is a Windows Phone device.

It will arrive in all the colors of Nokia's rainbow.

Ahtisaari discusses the handset's design, which has a curved back.

As with other Lumia phones, the screen is responsive to fingernails and gloved hands.

Apps like PhotoBeamer help Nokia stand out from competitors.

Nokia's built-in radio app makes an appearance as well.

Part of Nokia's "bold" move is to rebrand its mapping branch of the business to Nokia Here, and will continue to license mapping services to other companies, including the Firefox OS.

Navigation software gets you from point A to point B.

With a consistently flatter body, the Lumia 720 much more closely resembles the higher-end Lumia 920.

Nokia says that the Lumia 720 is meant for young people who want a stylish device, but who don't get fervent about high-end specs.

Nokia showed off some NFC accessories, like this wireless charging pad.

This iteration of the car charger takes advantage of NFC to wirelessly charge.

Only 15 euros (just under $20 at time of writing), the Nokia 105 is a very basic cell phone with a small screen.

Nokia CEO Stephen Elop jumped on stage to talk about pricing and availability.

Elop spoke at length about Nokia becoming a bolder player in the space, taking its services beyond handsets into business partnerships.
