Research in Motion and T-Mobile International have launched the BlackBerry 7230 in the US, following its debut in Europe two months ago.

The 7230 is a colour-screen, triband device that lets users access e-mail along with the internet and voice networks around the world. It was launched in Germany and Austria in June through T-Mobile, but is now available in the US for $399.99.

RIM improved the browsing capability of the 7230 with scalable vector graphics and support for Java applications. The colour display was also designed to minimise power consumption.

T-Mobile will charge $29.99 a month for unlimited e-mail and other mobile content, while the voice service fee is separate. T-Mobile is, so far, the only carrier offering the BlackBerry 7230.

Meanwhile, RIM's legal battles entered a new phase last week, when a federal judge issued an injunction prohibiting RIM from making or selling BlackBerry handhelds in the US. That injunction was immediately stayed pending an appeal, and RIM will continue to defend itself against charges of patent infringement by NTP.

NTP claims it owns wireless messaging technology, and the patents in question are being re-examined by the US Patent and Trademark Office.

RIM hopes to postpone the appeal until that re-examination is complete.
