Don't do it.
You won't like your phone as much.
SD cards are MUCH slower than internal.
But, if you must, it's in the app settings, I believe (settings-->app-->pick app-->move to SD card???)
Some apps won't let you move to SD card. There's no way around that. If it won't let you, you can't.
But, seriously, if you can avoid it, don't do it.
