can't deploy Xamarin project in iPod Touch

can't deploy Xamarin project in iPod Touch

I have some question about deploying project on Mac for iOS ( iPhone
simulators or iPod touch real device, attached via usb to iMac).
About my problem, when I'm trying to deploy - I've got such messages in
console at Xamarin Studio on iMac:
/Developer/MonoTouch/usr/bin/mtouch -sdkroot
"/Applications/Xcode.app/Contents/Developer"
-installdev "/Users/Sladky/Projects/tst/tst/bin/iPhone/Debug/tst.app"
