bluetooth for arduino?

i want to connect arduino uno to my android phone. can i use regular bluetooth  or i need to use some special?

Not sure what you mean by regular and special, but check this tutorial out and see if it would make sense:

I've had good luck with THESE modules in the past. They're cheap and easy to use. Once you have an Arduino, a BT module, and a project to do then follow steveastrouk's advice and just look at some of the arduino/BT projects already posted. If you have specific coding or usage instructions feel free to PM me or another author that has worked a similar project.
There are dozens of bluetooth arduino projects here. (some on the >>>>> of the page) take a look at them.
