The third incarnation of the Sidekick has arrived. Is it still hip to flip?
Expert review by : Stuart Miles (pocket-lint.com)
Loved by Paris Hilton and Everyone in the movie Be Cool staring Uma Thurmn and John Travolta, the Sidekick has a massive following in the US. Unfortunately that same following hasn't taken off in the UK, so is the latest handset, version three, about...
QWERTY keyboard, large screen, easy to set up email, web browser
Screen quality is poor, no business support, closed operating system so can't download more applications
We were actually quiet surprised with the Sidekick and its performance. It's not a Palm Treo or BlackBerry by any standard, however it is a simple alternative for people who want a QWERTY keyboard device without the business focus.

Coming at T-Mobile's Sidekick 3 with no preconceptions, it's difficult to know who it's aimed at.
Put brutally, we don't like the T-Mobile Sidekick 3. Couched in kinder terms, this may because we're old enough to be its father. The Sidekick does a lot of things, not always very well. But it will appeal to teenage users with no PC of their own - and...

Cooler than a Blackberry, but not as geeky as an MDA Vario, the latest Sidekick looks to cement its place as the most fun portable emailer in the world

T-Mobile has updated its Sidekick II with the not-too-excitingly-named Sidekick 3 (we wonder if T-Mobile thinks we can't cope with three Roman numerals?). If you are familiar with the former device then this update won't surprise ...
The Sidekick 3 concept is sound, and its automatic data backup and BlackBerry-like e-mail push both appeal. But as a Smartphone the device is unsophisticated in its capabilities. It is, perhaps, best described as a no-brainer Smartphone for the young...

In a PDA/phone universe dominated by Palm and Windows Mobile devices, the Sidekick (made by a company called Danger, but marketed exclusively by T-Mobile) has always been a maverick with a devoted, if small, following. To its predecessor's repertoire...
One of the best PDA keyboards around Offers stellar messaging features
Bulky shape Phone is difficult to dial
If the versatility that third-party apps afford and a petite shape aren't priorities for you, the Sidekick 3 is a good connected handheld for e-mail, messaging, and Web browsing. Heavy phone users might prefer a device with more straightforward dialing...

The T-Mobile Sidekick 3 is thinner and slightly smarter than its predecessor.
Extremely easy to use. Push e-mail.

T-Mobile Sidekick 3The limited edition T-Mobile Sidekick 3, which has been glammed up with Diane von Furstenberg style, is fun and functional. With Diane's signature hot-pink lips, this phone is super sexy, so I'm not surprised Fergie and Jessica...

Deutsche Telekom has added some grown-up features to its stylish phone, but this one still holds plenty of appeal for the MySpace generation.
If you've ever received a present only to have someone else in the house abscond with it and make it their own, then you'll know how I felt when I brought the T-Mobile Sidekick 3 along for a recent visit to my parents. Within minutes of my arrival, my...
