You can find updates, SD card images, and more at the Piper subreddit located here: http://www.reddit.com/r/piperwallet

Note: I have not released an update zip file for the latest software version (v1.06) yet, but I have released the SD card image.  So that means to update the software right now, you have to image your SD card with a computer.  I will be releasing an update zip file that you can put on a flash drive and stick into Piper to do the update without disassembling your Piper soon.

Thanks everyone!
