Hi guys if you were suspended by Real Racing 3 don't worry because it can be easily fixed.As such you don't need anything like tweak or jailbreak stuff.NOTE:This method was only tested with 'suspension code:10086'.If you have same code then this method will work 100% but if you have a different code I am not sure it will work or not.Just follow the steps carefully:
1.Open RR3 you will get the suspension message saying that you are suspended from accessing online features.......blah blah.
2.FIRST OF ALL LOG OUT OF GAME CENTRE.Open RR3,now tap the gear icon at left bottom of screen(settings) when you tap on the icon 6 more icons will appear.Tap on the gear icon(which popped out when you press settings) now logout of everything like facebook,google,etc.
3.Now just double tap home button and close RR3 from multitasking.
4.BOOM!!when you'll open the game you'll no longer see the suspension message.
5.Now you can login with another Game Center,Facebook,Google acount(Probably not the one which was banned cause if your login with the same one you'll get banned message again)If you have a jailbroken iphone just backup character.2.dat & player_profile.2.dat to anywhere like computer or any app to keep your progress safe.
HOPE IT WORKED FOR YOU!!
