During the account creation, I was supposed to call a phone number with my cell phone. Three numbers that I was supposed to call always have me a busy tone (yes from my Japanese cell phone in Japan). After numerous attempts, I quit. No account creation ability, i junk the program. (Coincidentally, just after regestering my email, I got a virus email from an email address in Japan but with a name from my contact list...). Fishy app
