and does this phone have the option of vibrating AND ringer AT THE SAME TIME?
No melody composer
Yes you can have it ring and vibrate at the same time. You can even have it vibrate to the beat of the ringer.
and can you add the ring tones with the usb cable?
I don't know anything about USB cables for this phone as I have never had a need for one.
Also what software do you recommend to use to create a ringtone?
Got any good links to some freeware?
