Microsoft on Tuesday slowly started rolling out its next Windows Phone 7 update, which, among other things, will bring cut and paste functionality to the mobile operating system.

WinRumors reports that the update, dubbed build 7390, was pushed to SIM-free, carrier unbranded devices. As a result, consumers with Windows Phone 7 devices from carriers like AT&T "may have to wait weeks," WinRumors said.

Canadian provider Telus said on its Web site that the earliest date any of its customers will receive the update, known as NoDo, will be March 29.

The update comes several weeks after the platform's first, minor update was met with glitches and delays, prompting the company to temporarily halt updates for Samsung phones. Given the problems, Microsoft later decided to delay this current update to late March.
