The Motorola Atrix is now available on T-Mobile UK, ending the handset's brief period of exclusivity on T-Mo's sister network Orange. T-Mobile is offering the Atrix for free on 24-month contracts of £35.75 or more per month, which is pretty much the going rate for dual-core smartphones in the UK right now. Opt for a cheaper or shorter contract, and you'll pay between £50 and £350 upfront for your Atrix.
There's no mention of the laptop dock just yet, but Orange has been selling them for £299.99 (~$490), so you can probably expect T-Mobile to get on-board soon at a similar price point.
