Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Sony Xperia Tipo (ST21i) supports up to 32 GB SD card. Any brand or class should work. I would recommend a card with class 4 or higher if you're planning to record lots of video.

I do not think you should go for 32,it seems a little too much for a single processor phone(800 mhz).
