I have this problem too. I had a fully jailbroken and unlocked iPad n I went n put it back to factory setting like an idiot Cuz I Thot that was the problem. It wasnt. So I lost all my jail break goodies n I still can't add friends. My husband has a jail broken iPad n his game works perfectly and he can add friends. I've gotten rid of apps deleted n reinstalled the game. I got rid of apps I don't use. I did all kinds of stuff. So idk what else to do. Is there a limit of how many ppl u can add? I'm up to 96 ppl now n I can't add n e more. Plz fix it!
