"You may not have realized it, but all of the cellphone calls you've been making have totally not been HD. While we may still be stuck with our old standard def calls for a while yet over here, it looks like the good citizens of Moldova have now finally vaulted into the future courtesy of Orange, which recently made the very first \"HD Voice\" call in the country (on 09/09/09, of course). Overused acronyms aside, the calls do indeed appear to be of noticeably better quality (at least if the web demo is any indication), which is mostly due to their use of the new Adaptive Multi Rate - Wide Band (or AMR-WB) codec that takes advantage of the greater bandwidth afforded by 3G. Unfortunately, it looks like the HD Voice-ready handset options are a bit limited to start with (just an Orange Moldova-exclusive version of the Nokia 6720), but it looks like more phones are expected to become available as Orange expands the service throughout Europe over the course of 2010.[Via GSM Arena, thanks Sathish]"^^<http://www.w3.org/2001/XMLSchema#string>
