Need help restoring phone!
I have my sister's old phone, she moved into an apartment in California. And the home button on my phone is broken, and the battery has been dead for months. I don't know the passcode on her phone. I want to restore it on iTunes, and create a new passcode, but I don't have enough access privileges for this operation. And I can't update iTunes, or download anything on my computer (Windows 8). What do I do?
iPhone 3GS, iOS 5.1.1
