By the way, I want to let EVERYONE know that, since I haven't been able to register wazapp due to the fail-too-many for over the last 3 days, I booted nitroid, then logged in to whatsapp, deleted my account, and waited for over 48 hours... Today I installed wazapp again and register still failed with fail-too-many, so I guess the only way to overcome this problem is apparentely to email the whatsapp staff and ask them to unblock your account. Some people also said that you can try waiting till the end of the month, though, I think it's better to take a few minutes and write an email to the staff than waiting 11 days till the end of the month without being sure.
cheers.
