Only phone and texts work
I had gone into restrictions and turned off what I could but then forgot my four digit password to get back in to change preferences on my iPhone 6+. I've never created anything except a long list of contacts that I do not want to lose. Unfortunately I can't save the information externally, turned off and never used iTunes. Never used any apps and had deleted all apps that were possible. How can I undo the restrictions? I think I will need to do that to pair up my Apple watch when it comes in a couple of weeks.
iPhone 6 Plus, iOS 8.3
