My friend code is ' 50pgj4 ' all the best in your builds. Remember, its only a game.
I have a cheat I want to share with everyone that i tried on sunday17june2012.
Firstly, THey may bring in an update to stop this from happening. What im about to tell you.
My phone is the desire s. Little experiment i tried and it worked. Airport city Game works being connected to the internet. So how does the game track your time? some buildings give you coins after 20mins ,some after 1 hour, some are 1 day. The game uses your phone to track the time you have to wait. If you advance the mins or hours. You can restart your phone, reload the game and collect the coins that you would of been waiting for. If you just change the time this little trick maynot work.I had to restart my phone. But i did this all afternoon. Gaining well over 10000 coins. Of course i dont have many buildings. I've been playing the game slowly NOT Completing the tasks or missions, just playing at my own pace.
I complete some automaticaly. (trying to get 3 stars in all destinations before moving on). But the more buildings you have the more you can collect when you restart your phone, then Advance the mins or hours, then reload your game and collect the coins. As i said,when this is found out a new update may stop this from happening. Just remember that is just a time wasting game. Please leave post of your phone if this little cheat worked or not. Please read on. Newer info.
I have the desire s. On this phone even if you have closed an app, its still running in the background. instead of restarting your phone as i said yesterday. For Desire S users, not sure if this would work on other phones. My phone sometimes take a while to restart, but try ding this. After you have closed the Airport city game. Goto home main screen. GotoSettings.GotoApplicaions.GotoRunning services.GotoAirport City.SelectSTOP. My phone shows 2 Airport Citys running i only have 1. if you have 2 stop them both. You now shouldn't need to restart you phone. Press back twice, or From the Main screen Goto Settings. Goto Date & Time. Then advance your minutes or hours or days. Your phone needs to show the different time. Now reload the game Airport City You can collect your coins, you can get your daily extras if you have advanced to the next day. You can do this over and over. I HAVE. Not been tried on the promo codes yet. Try that yourself. Back date your phone if you can. if you have missed 1. promo codes require internet so im not sure. You Try.
I have the SGS III and it works without restart. Basically you go forward in time and the game updates, I usually skip 3-4h and all it takes is going in and out of the game - make sure your wifi is off. Except when you cross the 00AM. Then what you need to do is automatic time and it gives you new coins. Otherwise I make like 20k coins a day if I am dedicated enough.
