O2 Xda Flint review


An interesting concept but is sadly flawed

Separate keyboard ; Haptic feedback helps with typing ; Large 5-inch screen ; Wi-Fi, Bluetooth and 3G

Too big for a pocket

A great piece of kit but we are unsure if it knows whether it's a smart phone or a netbook

O2 Xda Atmos review


The brick that means business

Slide-out QWERTY keypad ; HSDPA ; Wi-Fi ; Windows Mobile 6 Standard ; push email

Heavy ; only 2 megapixel camera ; average music player ; only 65,000-colour screen ; no GPS

A capable business phone with all the right work options, but limited fun potential

O2 XDA Venn review


A good texting/emailing device for the Windows Mobile lovers, with a very good battery. This might not be as good as the blackberry's for emails, the iphone's for toys or better at taking pictures than the 5-8MP phones out there, but as an all rounder...

O2 XDA Venn review


For a smartphone to still pack Windows Mobile 6.1 is nigh on criminal. But the O2 XDA Venn isn't any old smartphone. It rocks a unique dual slide feature that sets it apart from the crowd and makes it worth giving it a decent once over. So how does it...

Unique slide feature

Lack of basic features, Windows Mobile 6.1

The clever slide feature isn't enough to sae this very clunky old-school smartie

O2 xda II


Want a mobile phone and PDA in one handy package? O2's second Xda could be right up your alley.

If you already own an Xda, Bluetooth, a camera and some new software may not be enough to persuade you to upgrade.

O2 Xda Atmos


This is a very neat and user-friendly little smartphone, and is a credit to the Xda range.

Neat and small but still totes a sliding QWERTY keyboard.

The lack of a touch-screen can be annoying.

O2 Xda II


O2's Xda II combines a tri-band GPRS/GSM phone with Bluetooth, a digital camera, 128MB of RAM and a SDIO slot into a sleek Pocket PC-based device. Read our Australian review.

Abundant features ; Beautiful display ; Excellent build quality and finish

Pricey ; Network connectivity issues ; Missing Bluetooth profile

Business users and tech aficionados will see the allure of this device. It is an excellent PDA with phone functionality at a reasonable price point. Mainstream mobile users will find the Xda II overkill for their needs, both with its plethora of...

O2 Germany's Xda Diamond 2 is based on HTC's original Touch Diamond2 the Taiwanese handset manufacture announced back in February during the Mobile World Congress. It features the same squarish industrial design, unlike T-Mobile's MDA Compact V which...

PHONE EDITION: My two hours with the XDA II.


This is definitely a device to die for. I cannot possible find the right words to describe the feeling I had when I held the O2 XDA II in my hands. It was just unbelievable. Its sleek design with the familiar satin silver finish, its now bright and...
