This looks cool. I wanted to try it today, but the mobile store only seemed to provide me the option for 4.2-4.3. I was able to use the code with no problem, but now I have to wait for confirmation from mobihand to switch versions. That will probably take a few days from prior experience.
Another pleasant surprise. Mobihand is working OT on V day. Just got the email confirming the version switch. Didn't expect it so soon. Gonna check it out now.
