Installed App on Facebook. But to activate it you have to complete a registration where you also participaite in a contest with different prizes. When asked to enter cellphone no. the sms's starts to recieve several sms contest questions. It never stops. On the 3 sms there is added a line stating that this is not a subscribtion but a one time payment of $20. First time anything but the word "free" is mentioned. The sms's continue even after stopping the contest, and $6 is withdrawn from your acount each week. So if not suspected it will go unnoticed for about 6 weeks, until the first phone bill arrives and the bill is added $56 and before you find out what it is and how to stop it, you probely end up paying about $80. Don't enter your cellphone no. ANYWHERE on the net !
