News of what updates Windows Phone 7 will receive have been circulating since the release of the new phones but the latest leaks of the updates may be more insightful than previous rumors. The two major updates for Windows Phone 7 are codenamed NoDo (No Donuts) and Mango.
According to the report:
The first update: “No Donuts”
The first Windows Phone 7 software update, codenamed “NoDo,” will RTM in January, possibly this very week and in time for the CES keynote. But it won’t ship to users until early February, once the carriers sign off on it. This update will include the famed copy and paste functional addition, support for the Qualcomm 7×30 smart phone chipset, a CDMA location stack, and a number of software fixes.
“NoDo” stands for “No Donuts” and could be so named because the a minor Android update was called “Donut.”
Major update: “Mango”
While I’m not sure on the timing, the first major Windows Phone 7 update contains a piece called “Mango” internally; this will add Internet Explorer 9 with with the Trident 5 rendering engine, HTML 5 and Silverlight, and gesture support. This is the “75xx” code branch, which suggests that it could be called Windows Phone 7.5. (But probably won’t be … It actually calls itself Windows Phone 7.2 at this time.). Internally, this code branch is referred to as the “entertainment” branch, which suggests other, non-IE functionality as well.
The Mango is not scheduled directly after NoDo but is part of a future major update and other updates may be issued after NoDo, reports Windows Phone Secrets.
