Answers


Must be active, I've downloaded stuff from the Market place whilst my phone (HTC Desire) has gone to sleep, and the download has finished the next time I unlock (wake) it.


It's depend on application. By default in Sleep mode wifi state is inactive. Application need to take a wifi lock to keep it acive.


It depends on many factors, including those that others have metioned:

In your android settings, wireless settings, advanced settings- there is a wifi sleep policy which can somewhat answer your question.

However, an application (with the appropriate permission) can change this setting or temporarily change it to bypass the setting.

"Sleep" is pretty vague because some consider this when your display is turned off, however a device actually has different levels of sleep, and deep sleep. Deep sleep doesn't kick in as soon as the display is off, and often these rules are referring to deep sleep.

Applications can also obtain a wifi lock (with the appropriate permission) which will wake up the Wi-Fi radio even though the phone is in deep sleep.
