When I got phone it was sync to his computer which I have no access to. Want to know if he has access to my text and stuff
Your post is a bit confusing. Are you saying you bought your iPhone from someone and want to know if he has access to your data? If you created a new account, then he has no way of getting to your information.
I'm guessing the OP is referring to her husband on whose computer her iphone is syncronised with iTunes. As far as I can tell itunes does not store texts, etc. emails are only syncronised if you have set them up to do so. iTunes essentially only syncronises downloaded apps, music, videos & pictures, & the phone can only be browsed when it is connected, but again this does not include texts & emails.
