My whatsapp was going to expire this month, the 27th and according to them, I was suppose to pay for the next year. I got myself ready to uninstall the app when that happen, cause I'm using Gtalk more.
I just got a message: "Whatsapp service extended". Ichecked whatsapp account info and saw that my expiration date is now 11 of August 2012. So I got an extra 8 months.

Anybody else got their service extended, gratis?
