Last week the Windows Phone Blog confirmed that the Mango update would be shipping to devices within the next 2 weeks, but more evidence suggests that it could start as soon as today.

We’ve heard from various sources that the Windows Phone 7.5 rollout could start as soon as today for some customers, there doesn’t seem to be a pattern as to which handsets on which networks will receive it first. Yesterday many people found that the regular update process of devices had been disabled. Also last night a leaked AT&T memo was seen stating that today, September 27th, would be the start of rollout for their Windows Phone 7 devices.
