How to get into an iPhone that is already disable?

So i left my phone at my friend's appartment, then my other friend came and changed the passcode as a prank for me. My friend who owns the appartment tried to get into my phone leaving me only two chances. So i didn't know that the passcode has changed so i entered the initial passcode, it says that it is wrong. So my phone was disabled for 60 minutes. Then i re-entered the passcode i knew, cause i thought that i miss typed it the first time. Then my iphone was disable and it says connect to itunes. Then i just realized that my iphone is registered to my cousin, who gave my this iphone as a gift originally, to her mac. And she an hour away from me, by plane… Fml. And i don't think i'm visiting her until winter break, which is not until december. What should i do?

All I know you can do is reset your iPhone. Or get iTunes on your laptop and sing in with your cousin's iTunes account and connect your iPhone and it should be good.
