Priced at $299 with a two year contract.

The T-Mobile Sidekick 3 has finally arrived. No, it’s not a super phone—it does not aspire to imitate your home entertainment center (though it does now have an MP3 player). It remains true to its roots.

“The Sidekick is a communication device,” says Jeff Folino, head of product development at Sidekick. “It’s all about email, two-way and phone. The hip-hop community calls it a ‘ménage’ (as in ‘ménage a trois’). The rate plan is affordable. And, it does what they want it to do. It’s not trying to be anything but what it is.”

Folina says the new version is a result off “asking the users what they wanted.” And, the Sidekick team delivered. The 3 supports IM clients (AIM, Yahoo! Messenger and MSN Messenger), boasts a better browser (thanks to EDGE), and has built-in Bluetooth support for wireless headset use and vCard exchange. It’s also 20% smaller than the II, weighing in at a mere 6.7 ounces.

The Sidekick’s demo is 18-30-year-old “trendsetters,” according to Greg Andrews, director of marketing. “They are always connected. They are information seekers. They want to be in the know and in touch.”
Sidekick addicts can get the new version for $299 with a two year contract or $349 with a one year contract.
