Following the release of homebrew "NoDo" updates, Microsoft today has published an update on the Windows Phone 7 saying, "We've started delivering the March "copy and paste" update to customers of O2 and SFR in Europe. Also, Telstra customers in Australia are now receiving the February update. See Where's my phone update? for the latest status," stated Eric Hautala.
"We're working hard to get this job done as quickly as possible. But I've noticed that some of you're turning to homebrew solutions to update your phone immediately. As an engineer and a gadget lover, I totally understand the impulse to tinker. You want the latest technology and you're tired of waiting. Believe me, I get it.
But my strong advice is: wait. If you attempt one of these workarounds, we can't say for sure what might happen to your phone because we haven't fully tested these homebrew techniques. You might not be getting the important device-specific software we would typically deliver in the official update. Or your phone might get misconfigured and not receive future updates.
It's even possible your phone might stop working properly. Bottom line: unsupported workarounds put you in uncharted territory that may void your phone warranty. We've made a lot of progress in recent weeks, so I urge you to please be patient for just a bit longer and wait for your official update notification to arrive."
