BFL_Jody the customer service representative from Butterfly Labs has made a blog post asking people who have pre-orders with trade-ins to please start sending their FPGA bitcoin miners back to Butterfly Labs for processing adding "With Josh's return today with chips in hand, I feel comfortable with talking about trade-ins."

Jody has offered a few ways to proceed for people with FPGA trad-ins for their new ASIC devices;-

First (and most obvious) send tour FPGA devices back to their new address ( Butterfly Labs, Inc., 10770 El Monte, Suite 101, Leawood, KS 66211)

Second, pay a deposit for your old FPGA devices of 20 BTC for a single and 500 BTC for a Mini Rig and keep mining with your FPGA devices until your ASIC devices arrive and only then shipping back your FPGA devices. On arrival of your FPGA devices Butterfly Labs will refund your deposit.

Third, Butterfly Labs will hold back part of your ASIC order until your FPGA devices arrive back at Butterfly Labs.

After many months of waiting and hoping it finally seems that Butterfly Labs is on the final stretch in the race to bring ASIC bitcoin miners to the public and I know a lot of people in the community will be relieved to know that the wait may soon be over, even though Butterfly Labs seem to have come in last.

The full open letter to customers is contained below.
