I recall seeing the Modu mobile phone at CES a few years back and thinking it was a cool idea. The device is a tiny cellular phone module that you can slip into various different cases to completely changes the device and its interface.

A new Modu phone has surfaced and it is called the T-Phone. The device has a touchscreen and looks like a slick little interface as well. The handset is the first from Modu to have 3G connectivity.

A few months back, Modu was showing off a cutesy little phone at Mobile World Congress and creating quite a stir. And here it is now available on the market. Mobo, an Israeli website has already done a hands-on. Here’s the basic low-down.

It sports 2.5G, no WIFI. The phone consists of two pieces: the “module” that houses the actual phone and the “jacket”, which is a physical shell/case. You can switch “jackets” as often as you like. The available jackets are a little basic at the moment, but should get better.

Envision if you will for a moment a mobile phone which lets you change it up somehow so that it meets your “changing needs, preferences and style- easily and affordably.” That is the idea behind a new mobile phone ecosystem announced today which is called modu.

Several sets of products make up this new ecosystem. At the core is the modu itself, a tiny mobile phone. This modu phone can be used enclosed in design focused phone enclosures called modu jackets and enhanced via modu mates – products from mainstream consumer electronics manufacturers who will be developing special MP4 players, digital photo frames, cameras and DECT phones, among other items.
