Ok so today I couldn't send any messages on my iMessages on my iPod touch 5th generation and I stupidly turned off my iMessage and my brother won't give me his password( I'm using his account). So if I change the Apple ID would everything restart on my iPod? If you guys knows this PLEASE do tell me because I'm going crazy from this!!! And would it change the email to every single thing on my iPod like Game Center, my itunes stuff? PLEASE IF YOU KNOW WHAT TO DO PLEASE PLEASE TELL ME!!!!!!!!! And will it change my app thingy like will the account change on everything including getting apps? Thank you guys!!
