You can scale iOS simulator to desire scale (i tried from 0.2 to 1.4 ) and it worked for me.
To do this you have to go to /Library/Preferences and edit com.apple.iphonesimulator.plist file. Edit value of KEY SimulatorWindowLastScale to your desired scale.
I tried this on latest Version of Mountain Lion 10.8.4 & iOS simulator 6.0.
Enjoy!!!! Let me know if it worked for you guys.
