I upgraded yesterday to the 6+ from my launch day 6. I cracked the screen on the 6 and it gave me the excuse to get the 6+ that I should have bought in the first place. I put the cracked screen 64 gig 6 up on ebay for $550 and sold it in less than an hour.
 
Good luck! I just listed mine also and it got approved in about 20 minutes. I like Swappa already!

Just as an experiment, I listed a Buy It Now on eBay for about $35 higher. I'm curious to see how the two compare as far as offers go.

Just an update to those who are curious, the eBay listing won. Sold this AM and my net is about what I was expecting on swappa (give or take a few bucks).

I think it would have sold on swappa eventually, but there are just way more eyeballs on eBay. When I cancelled the swappa listing it had about 30 views after 3 days, where the eBay listing had that in less than an hour.

I really want to like swappa and I hope it catches on. It's better for buyers and sellers (although I'm not a fan of the rigid condition classification system they have). I'll probably do another dual listing in September when I upgrade to the 6S Plus.
 
However you sell it, make sure to pay extra at the post office for insurance/tracking/signature on delivery to protect yourself from fraud. You might want to include this in your price and let the buyer know in the description that the price accounts for all of it which could scare away any scammers.
