Bluetooth module for Arduino uno

Can someone suggest cheap bluetooth modules for arduino uno?

I just need to connect my phone and arduino uno via blueooth and send phone's accelerometer over it.

That is assuming the phone is an Android. If it is, it's pretty painless..

This probably applies to a windows phone too, but nobody talks about that.

If it is an iPhone, you will need something else, like a BLE module.
