Ok guys, I need help. I am a long time iPhone lover and I have gone threw 3. I bought the iPhone 4 when it came out and saved my iPhone 3 for back up. Now I've never needed it until now but it's for my little sister since someone stole hers at Six Falgs(I personally think she lost it on a ride, but thats besides the point) Now Im letting her have it instead of buying a new one since its laying around. But here's the thing.... I FORGOT MY PASSWORD!!!! AND IT HAS NO ACTIVE SIM. So my question is, do I have to take it to Apple to get into it, the AT&T store, or is there an at-home trick to unlocking it? Please all tips and help is welcome.
