Zombie Infection (Splinter Cell, Hero of Sparta and PoP) cant be free be because it's new games and Gameloft cant earn money on this games.
Just go to "Settings" then "Mobile". Once you set up your phone with twitter, all you will need to do is go to Gameloft's twitter page and turn on SMS updates. To do so, just click the little picture of a phone next to where it says "Following".
Twitter alert does not work in Hong Kong. Just hope Gameloft will FREE the game per day. So it will be Happy Day, not Happy 2 hours.
I think we can start to expect a release at any point soon since it'll be daytime on Monday in Australia/NZ pretty soon. I guess it just depends on which location Gameloft is going to focus on. I have GL twitter updates set to text me, so hopefully I can wake up and DL a free game if its the middle of the night in the US.
I just put the free RSS reader on my phone. Only bad thing is it doesn't have push so I still have to check it, check it, check it. Hopefully we'll get some warning.
