Here is the tripod stand I made for my Captivate. Best of all it was $0 free.
I cut and bent a piece of metal I had laying around for the bracket. Then drilled a hole in bracket and glued in a nut I had laying around from another project to attach bracket to tripod. Added self adhesive backed foam weatherstripping for padding and so phone would not get scratched. Had a mini tripod that was given to me and I was not using because I have a full size tripod.
I could have made it look nicer but this was a quick test to see if it would work.
I think I spent more time thinking about how I was going to make it then I spent making it.
It holds the the phone so well I can turn it upside down a shake it and the phone will not fall out.
