Sidekick 4G review


It's been nearly two years since we last reviewed a T-Mobile Sidekick, and it would be a vast understatement to say things have changed. Then, they were

Stylish design ; Great QWERTY keyboard ; Fantastic value for the price

Smallish screen ; Social networking integration is flawed ; Slightly slower than Galaxy S handsets

T-Mobile Sidekick 4G review


You thought Sidekick was dead, did you? That'd be an easy assumption to make since Danger's servers are being turned off this month — and since it's the one of the most deeply-integrated cloud...

Stellar keyboard ; UI skin is, against all odds, not annoying ; Rock-solid hinge

Thick ; Plasticky ; Odd control / port placement (not a big deal for old Sidekick users)

Android has grown up — and T-Mobile’s lineup of Android devices is finally mature enough to support this kind of tightly-focused hardware

Review: Samsung Sidekick 4G


The Sidekick is reborn as a fast Android phone, but it's got a few too many quirks to succeed.

Physical keyboard will keep thumb warriors happy. Tons of media options and chat features keep you entertained and connected. Speedy 1-GHz Hummingbird processor gets things moving: Games like Angry Birds Rio don’t stutter in the slightest. Battery life...

Screen-popping mechanism is a bit tricky. Button placement is downright poor. The mix of onscreen-touch and physical-button navigation is perplexing and redundant. It takes a lot of work to get a good photo –- if I wanted to mess with that many...

T-Mobile Sidekick 4G review


T-Mobile Sidekick users were probably a bit stunned when it was announced that data service for the popular messaging handheld would cease on May 31. Though the interruption of service is certainly inconvenient, it doesn't mean the end of the...

The T-Mobile Sidekick 4G impresses with the addition of a touch screen and the Android operating system. The handheld also offers enhanced messaging features, great call quality, and a good camera.

The user interface won't appeal to everyone. The smartphone can occasionally be sluggish.

The T-Mobile Sidekick 4G continues the Sidekick's legacy as an excellent messaging device and also serves as a great entry-level smartphone.

T-Mobile Sidekick 4G


The T-Mobile Sidekick 4G has the best keyboard you'll find on any Android smartphone.

Excellent keyboard. Fast Internet. Well-built hardware. Unusual, great-looking UI design.

Awkwardly placed Power and Volume buttons. Some glitches in the setup app. Strong design flavor not for everyone.

Conclusions The T-Mobile Sidekick 4G isn't a Sidekick. The Sidekick was a device with a cool, simple OS and swiveling screen. That platform is dead. Instead, what we have here is a Sidekick-inspired Android phone with an awesome keyboard, a...

T-Mobile Sidekick 4G


It's baaack. The T-Mobile Sidekick has returned (It00 with a two-year contract from T-Mobile; available April 20, 2011), and this time it has 4G speeds. As a former Sidekick LX user (and honestly, I kind of miss good physical keyboards), I was excited...

Superb keyboard ; Excellent messaging features

Design is a bit on the heavy and chunky side ; Camera is just average

The Sidekick might not have the specs to compete with some of the high-end super smartphones out there, but it is excellent for social networkers or first-time smartphone owners.

T-Mobile Sidekick 4G Review


The Sidekick is back in a big way. For just $99, this well-designed Android phone offers a wealth of messaging features, fast data speeds, and a superior keyboard, making it a great choice for smart phone hipsters on a budget. Android purists who crave...

Excellent keyboard, Advanced messaging features, Fast data speeds in 4G areas, Long battery life, Affordable price

Non-standard Android interface will confuse some, Occasional lag, Awkward power button placement, Some glitches with Group Chat feature

The T-Mobile Sidekick 4G has a lot to offer including the Android OS in a fairly compact package.

T-Mobile Sidekick 4G Review


The original Sidekick was one of the first mobile phones to become a gadget icon. That said, it was really the Sidekick 2 and 3 that took off, ...

Fast 4G Speeds, durable hardware, solid performance, great display, camera lacks a flash, solid multimedia and social media integration

A bit on the heavy side, no built-in memory, doesn’t come running Gingerbread, interface and plethora of buttons is a bit confusing to operate
