I Belive that my iphone 4 messages have be hacked. how can I be sure to fix this problem or tell for sure?
are you talking about emails or text message.
Only way your phone can be hacked is if your phone is jailbroken.
If it's email just change your password.
You can't get hacked thru text.
unless you have jailbroken your phone, highly unlikely... What is happening to make you think that? And have you or the previous owner jailbroken your phone?
I am talking about text messages.
No the phone has never been jail broken.
