Just a note for all those interested, I received an email from HTC today stating that they were extending the cut off date for the trade up program to June 19th.
However, If you didn't sign up for the preorder deal before April 4th, you may not be able to take advantage of this deal.
This is from the upgrade program terms of use page section 8 paragraph two "To receive the $100 trade in value (or actual device trade in value, whichever is greater) in exchange for the Device you trade in, you must register valid email address on or before April 4, 2013 at HTC OneTM Upgrade site, you must purchase and activate a new HTC One by May 19, 2013 and mail in your used Device with a valid Proof of Purchase of your HTC One (copy of UPC or invoice/receipt showing the IMEI) post marked by June 19, 2013."
I just unrooted my Evo 4G, pulled the micro SD card ( I gave the 8 gig one that came with it to my sister a while ago and sure as heck wasn't about to give them my 32GB card) threw a charger plug and a beat up HTC branded usb cable in the box along with my proof of purchase for the One and the trade up voucher which I printed off in a box and put it in the mail. Hopefully it gets processed and I get my $100.00 in a timely manner. I did contact HTC to ask if they would take the phone rooted, without a battery, without a charger and cable, and without a card, they said yes, but the terms of use page clearly stated that the battery, and charger MUST be included with the phone, so rather than take a chance on it, I threw them in with the phone.
