I'd say full sun. But.
Did you *just* transplant them? I know it looked like I killed our new blueberry bushes for about 2 weeks after I planted them - they were in transit for a few days and I planted 'em the day we got them. Took 2-3 weeks for the stems to get back to green (yes, they turned brown!) and now I'm getting a few leaves!
The blackberry canes I got the same day and planted the same day were basically just big sticks, and we just got 2 little green leaves on one cane in the last few days. So they may just need more time to acclimate.
