You could kind of say I got paid to get an iPhone! When the iPhone was announced in January we had just switched to Verizon. My wife and I decided
to switch to AT&T to get the iPhone and coincidentally Verizon changed their contract and we were able to get out of our contracts (that were less than 3 months old) with no early termination fees... and we kept our phones.
My Verizon Treo sold for about $300 and I got a temporary Treo 680 to tide me over until June. It sold for $280 on eBay (it was free from Amazon). So I got just about enough to cover the cost of my phone.
My wife sold an old beat up Powerbook. She was going to sell it anyway, but it just so happened to sell about the same time that we got the iPhones so it was pretty much a wash.
Still, I was buying them regardless... even if I had to pay a termination fee I was getting an iPhone the day they were released.
