The app doesn't work on my USA phone. I keep getting an error code, "Error sending SMS please try again (500)". I rated the app a 1 star on the Play Store.
Edited to add. I finaly received the activation code aobut 1 and 1/2 hours later. Entered the code and it's working. No $5.00 worth of bitcoin. Guess I am not one of the first 1,000 user.
Seriously, why in the world would KNC want their own wallet program? Is this another move to get their greedy little hands onto even more BTC? One day you'll notice all your BTC is gone and you'll have to fight to get it back. Stick with the Armory and you'll be safe. Have to question their intentions and motive on why they want their own program? How does it benefit them?
