Where should I go to unlock my iPhone 4 (with ios 7)?

Today I left my pass-code protected phone on my desk. My friend stole it and kept it with them for the whole day. I knew they wouldn't lose it so I didn't mind. But then when I got it back at the end of the day he had used up all of my attempts and a little message told me to connect to it with Itunes. I tried that but iTunes said that it could not let me access my phone because it is locked. I did some googleing and it said that I need to go to the store. My question is, would I have to go the the Apple Store to get my phone reset or just go to my carrier, Verizon?
