Still wating for mine....found this today. Settings,about phone, tap android version a few times quickly. Touch the image that appears then long press the next image...have fun!
I also just got off the phone with them and he told me that It will be the s2 watch and it will ship 4-6 weeks from 4-8-16... weird cause that email was sent to me 3-26-16.
I have not gotten conformation emails either but I did email PL and ask if they could change to the s2 and they sent me a confermation email statinf they were able to change my prize to the s2 watch.....
