I got my iPhone 4S off eBay, brand-new. (The other iPhone 4S, I sold the whole thing + the logic board.) It didn't come with a SIM. So being me, I erased all content and settings, but when I go through the setup, it says that I need a SIM card, SIM required, please insert a SIM card. My SIM card for AT&T comes in the mail in about 2 weeks. Until then, I want to use my iPhone as an iPod. There is no iCloud lock on this iPhone. Is there any way to bypass this?
