IPhone Help Browsing History?

I just sold my broken iPhone on ebay, the screen works but the touch screen doesn't.So, because if it at the defult grey iPhone screen (i forgot my password so i reset it) will all my private browsing history, notes and apps be on there for when he buyer rpairs the phone.

Unless you did a full data wipe (not just a factory reset) it will be possible for someone who knows what they're doing to recover all the data from your phone.
