I don't understand why would anyone use a random, insecure, proprietary chatting solution as WhatsApp, when you have so many safe and open alternatives. Please, don't use it. If this doesn't convince you, read more here. The worst thing is even if you don't use it, it takes one ***** who does and has your number in his/her contacts and your number is uploaded to servers of this insane company for 'anyone interested' to read. Thumbs up for everyone supporting WhatsApp on Maemo. NOT
