Would you like to your favorite song to be your ringtone for your Blackjack II? Here's the steps to get this going.
So far, it seems like you need to get your MP3 over to your Main Memory and not your SD card to make it a ringtone. Once you get the MP3 over to your phone, you can go to Settings, Sounds, RingTone and select the MP3 as your Ringtone. If you don't see your MP3 and it's on your phone, wait 5 minutes and look again and it'll probably be there. :)
If you have Outlook contact you can now open the Contact and select the individual ringtone. This won't work for SIM contacts.
