Yellow pages in USA have released a pretty good Windows Phone 7 app recently, but obviously this is not very useful outside the country.
A reader has written to let us know the company expects to release a UK-specific version some time in the next 6 weeks.
In response to a query Yell UK said:
Thank you for your email regarding the Yell.com apps, I am pleased to confirm there is an app due for release to the Windows phone hopefully the end of May to the middle of June.
Support by big names companies is pretty important for a healthy app store, so the addition would be more than welcome.
