Cashforiphones.com offered me $192 for an iPhone 3g in excellent condition. I sent it to them, and a month later received an email stating that they were going to pay me $80 for it, and I had seven days to contact them to accept or reject their offer. I made several calls to them, I sent them an email (twice) telling them that I did not accept their offer and wanted my phone back. No response. I suspect that they never intend to answer the phone, because that'll take away all the unnecessary holding for 30+ minutes and that way. They can also use it as an excuse to say that I never contacted them and accepted their low-ball offer.
