The 7392 build of Windows Phone 7, the latest to date, is the one that comes after the NoDo update and applies some fixes to Internet Explorer’s vulnerability regarding the fraudulent certs affecting some websites.
In its weekly “update on the updates” post, Windows Phone Blog announced that Microsoft is scheduling the 7392 build for AT&T HTC Surround users, with other models to follow. As far as the Samsung Focus is concerned — which gave a couple of headaches to everyone –, Redmond is “actively scheduling the final set of tests” after which the roll-out phase can come for “Focus handsets with the alternate memory”, with no exact date being specified though. Last but not least, if you’re on Orange and have a Samsung Omnia 7, the updates are rolling out again as the process has been resumed.
