T-Mobile Sidekick 3 mobile phone - Pocket-lint


A messenger for those without the need to stay in touch the office, this is a good all round package if not a little dated in its looks

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.

T-Mobile Sidekick 3


The third incarnation of the Sidekick has arrived. Is it still hip to flip?

T-Mobile Sidekick 3 mobile phone


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

The Sidekick retains its title as portable emailing’s cult hero. Half-hearted multimedia extras don't add much, but on-the-fly messaging has never been easier

T-Mobile - Sidekick 3


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...

T-Mobile Sidekick 3


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...

T-Mobile Sidekick 3


The T-Mobile Sidekick 3 is thinner and slightly smarter than its predecessor.

Extremely easy to use. Push e-mail.

T-Mobile SideKick 3


T-Mobile adds some cool new features, but this feels more like Sidekick 2.5.
