1. Yes and yes

2. Can't help you with that one...

3. Again, can't help there.

I love my iPronto, but one area of functionality which the keypads have over the iPronto is that they respond instantly. With iPronto, when you first activate it from "sleep mode" it takes about 10 seconds (approximate guess, I've never counted!) to establish the WiFi connection, so button presses take a while. Only the first one. As long as it stays awake, the connection remains and subsequent presses are more or less instant. Not trying to put you off iPronto, just something to be aware of....

NB This does not apply to IR commands, only WiFi ones.
