I just recently bought a mini memory card for my phone to put songs on it. I have a T-Mobile Samsung Gravity. So I was just wondering what file extension do the songs need to be in so they will play on my phone and where I can set them as my ringtone.What file extension would I use for the mini memory card for my phone?mp3 or wav is pretty much a standard nowadays... if your phone can play a simple mp3 song, then... just wow... i have nothing to add to that.. just wow...
