Everyone’s anxiously waiting for the huge Windows Phone 7 upgrade to arrive, both in terms of the upgrade to existing phones as well as new phones with new hardware features. Eric Hautala just posted to the Windows Phone blog that it will be coming in the next week or so. That’s kind of vague because it sounds like it will be the same kind of thing where certain carriers and certain devices will get the upgrade at certain times. It won’t be an all at once thing. Eric also recommends against installing unofficial versions of the update since each device and carrier specific update will be including special customizations that tune your device for optimal usage.

In other words, if you used the Mango for all hack to get the Mango beta on your phone already, plan on restoring your device to the official NoDo build in order to get the real upgrade.
