This is my favorite website now.
When I formatted my SD card to internal memory it automatically transferred everything to the card memory. Anything I install now goes to the card. I don't think I did anything specific to it.
I got this one, I don't use the Cd player so it's perfect. Never falls out.

I've had the 7 - 8 - 9 & 10 I've loved them all even tho the 9 got a bad rep. All unlocked from HTC except for the 7 got the 64gb from att. But I have to say that I have no interest in the ultra at all. I hope this helps your friend.
