The Samsung Focus — 1.4 version on AT&T — is finally getting its Windows Phone 7.5 update, according to the official Windows Phone Blog update post. The refresh has been fully tested and Microsoft is expected to flip the switch any time now. The update for the Samsung Omnia 7 on Telefonica in Spain is also being scheduled.
Additionally, some devices from specific manufacturers are expected to deliver special updates which apply to certain models only. These bring bugfixes, improvements and some of them enable Internet Sharing. In addition, Microsoft is planning an OS update — build 7740 — for Vodafone, Orange, and Deutsche Telekom customers in Europe. This fixes “an issue with new voice mail notifications not appearing for customers on some European and Asian networks under certain conditions. It also fixes an email issue associated with Exchange Server 2003”. This update is currently being assessed by carriers and should go live as soon as they give it a go.
