i found that my razr will record sounds in mp3, and when i send that sound over as a txt message i have the opportunity of saving it as a ringtone on my new phone. new phone is the lg enV. same with my friends razr, she has some ringtones that are mp3s and i was able to send them to my phone and convert them. doesnt work with the midis tho, not sure why. and i know verizon blocks adding ringtones with bluetooth right now, something they used to allow and advertise with their connectivity kit. now the kit only makes it a modem i guess. i cant see muchc use for it otherwise. my new one also ha the flash card, so i can add any wallpaper i want as long as the phone is able to show the resolution. up to 1600X1200 is what mine will handle, but the razr will only display 1280X1024. most of this is up to what phone you have.
