So you have an Env2. Plug the USB connector into the phone and into the computer. If you have a micro USB, you should use this. If not, you will be using the phone's internal memory. You should download the program called BitPim, and I use it for my Env2. http://www.bitpim.org/help/You should really get the MircoSD, that way you can add music directly to the SD and then just stick it into your phone.
