T-Mobile's Nokia Supernova 7510 doesn't offer a lot on paper, but it remains an intriguing cell phone in a couple of ways.

The chunky flip phone comes in three colors--brown, fatal red, and espresso--but you're not married to any one hue. The front covers are removable so you can change colors as often as you like. Nokia says the phone will come with one cover attached, but you should get another cover in the box.

The Supernova's skin has a smooth, soft feel and the phone feels comfortable in the hand. The exterior controls are about what you'd expect. There's a volume rocker, a camera shutter key, and the headset/charger ports.

The 7510's external display is its most eye-catching feature. It is invisible when the backlighting is off, but when it's lit the numbers and text are large and visible. The display also has nifty animation that flashes intermittently.

The interior is silver and shiny in the style of the Nokia 6263. The display is big and bright and the controls are tactile.

The feature set is solidly mid-range. It includes a 2-megapixel camera, a music and video player, support for T-Mobile myFaves, messaging and e-mail, instant messaging, Bluetooth, an expandable memory slot, a speakerphone, and a personal organizer. It also has integrated Wi-Fi for use with T-Mobile's HotSpot @Home service.

The Supernova 7510 should be out by the end of the month.
