You should be able to, it just takes a little while to link it.
When you go into the box to type in the "code", there's a link in the box. What you will want to do is paste that link in the search box of a new tab. That should allow you to find all the Bluetooth devices close to you.
Trying to track down the individual code is a little tricky, generally just guessing and checking will work the best. Once you have found the right code (and made sure the cube is in pairing mode) you should be able to start solving just fine. Unless this info is just useless and it only works with the iCarry, but I'd seriously doubt it.
