I thoroughly checked it out beforehand, checked its water damaged strips, played with it, and decided to get it. The phone is awesome and it's working terrific, but I noticed the Earpiece speaker was really soft. After checking online I've come to realize this is a common defect among iPhone 4S and is something they'll replace under warranty at the apple store. To make a long story short: I plugged the phone's serial number into apple's website and this popped up: Were sorry, but this is a serial number for a product that has been replaced If your information is correct, you may need to contact us. Um, what the hell? The kid I bought it from was a really straight laced kid and not the shady type. What's more, the phone was in immaculate condition and without a single physical flaw, so I don't buy that it was stolen. Does anyone know what this means? It's freaking me out. I bought the phone to use on straight Talk's $45 a month iPhone plan with unlimited everything and it's working terrific. I didn't think there should be anything wrong with buying the phone used as I knew what to look for and this phone is in ace shape. I'd like to get a replacement phone to fix the headset speaker issue but since the phone otherwise works perfectly if somehow bringing this to the attention of apple causes my phone not to work anymore or be disabled or something, obviously I can live with the stupid headset speaker being busted. What do you guys think? Ever heard of this issue? What should I do?
