According to winrumors AT&T is done with testing Windows Phone7 and would be releasing its update on some devices by Today (April 19). We’re talking about the NoDo update here, so Mango hopefuls are out of luck this time. An internal email of the support personnel of the carrier gives the info about this update.
This upgrade is meant for the smart phones LG Quantum and Samsung Focus, while HTC surround will get it later, most likely im mid-May. The internal memo at AT&T mentions a first install of the Maintenance Release (7008) software, allowing the device to accept the NoDo update (7309). Customers will get notifications ahead of the release, letting them know about the update.
The Copy/Paste functionality is an important feature brought by Nodo and AT&T is claiming that some extra features exclusive to the carrier will be included.
