7.9/10
Informr score
The Sidekick 4G currently has an Informr score of 7.9 out of 10. This score is based on our evaluation of 15 sources including reviews from users and the web's most trusted critics.

The latest iteration of the Sidekick runs on the new, 4G network and is powered by Android 2.2. Retaining its unique sliding approach, a fast horizontal spring-slide that leaves the screen at a slight inclined angle, the Sidekick 4G offers a 3.5 inch touchscreen generating an impressive 480 x 800 pixels. Of course, you also get a full and spacious QWERTY keyboard.

Packed inside this now iconic phone you'll find a 3MP camera, video record, and a second camera for video calling. Add an MP3 player, native YouTube support, full internet browser with Facebook and Twitter support, and you have a fun slider packed with features people want.

But this latest version of the Sidekick offers some surprising additional features, such as tethering and DLNA support, putting it squarely at the top of many customer wish lists.

Rounding out the feature list you'll find GPS, Bluetooth 3.0, WiFi, expandable memory up to 32GB via microSD, and the always welcome 3.5mm headset jack.

To this writer anyway, it looks like the Sidekick has grown up gracefully, and continues to be relevant as a smartphone option full of fun and productive features that will keep any user busy and fulfilled for some time.

The growing Android empire has legions of slatephones big and small, and a growing stable of physical QWERTY devices led by the likes of HTC's G2 / Desire Z, Samsung's Epic 4G, and of course the Motorola Droid 2. All of those play at the higher end of the market, though, where folks can afford phone...

Looked at solely on its own merits, the T-Mobile Sidekick 4G is a very solid device. It's got nice build quality, a great keyboard, fast performance, and an ergonomically comfortable design for messaging. However, it's when you look at the device in the context of its $100 suggested retail price tha...

The Sidekick won’t appeal to everybody: it’s no dual-core, large screen, enterprise-heavy super phone. But then again, that’s not really what the Sidekick brand is all about. It’s not really meant to be used in the boardroom. The Sidekick was designed for social networkers, f...

As an old Sidekick user, I can confidently say that this will definitely appeal to Sidekick users from days of yore, and it might even steal some of the kids who flocked over to BlackBerry when Sidekicks started slipping and taking a back seat to everything else. Even though it’s made by a new...

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 a keyboard will likely prefer the T-Mobile G2 f...
