Now I've been getting this whenever I open my iPhone ever since a friend of mine went inside my General settings and put in a Password Code to open iPhone and forgot the 4-digit code...

So after trying to find the code, it said to try again after 1 minute, 15 minutes, 1 hour, and ultimately now it just says to "connect to iTunes"...

My phone is unlocked in v1.02
is there anyway I can reaccess my iPhone? If so what can I/should I do?
