I sold my iPhone 3G today for $350 via Craigslist. My iPhone 3GS will be arriving next Friday. I don't have a backup AT&T phone so I wanted to suspend my service for a week. My question: Will suspending my service (aka reporting it lost/stolen via OLAM) affect the buyer of my iPhone 3G? Will it lock him out? Will it raise any red flags to ATT? Just want to make sure I don't set a chain reaction of events by doing it.
