I bought a MBA recently. So I'm wondering, after I upgrade to the free Mountain Lion - which OS will I get if I wanna use the internet recovery for clean install? Lion(pre-installed) or Mountain Lion(the free upgrade)?
Well, mountain lion will instal its own recovery partition so if you use that (command + r on boot), you will get ML. It will prompt you for your Apple ID.
If you bypass the internal recovery for a pure internet recovery (command + option + r) or your recovery partition does not wok, hmmm...I'm not sure which one it would use.
Hopefully it is smart enough to ask for your Apple ID and if you have purchased ML it installs that.
This is a new situation so I dont think anyone really knows yet...
