Questions on Notification Sounds

[volsmcfalls]

I have a few questions I was hoping you guys could help me out with.

1) does the notification sound for a text message have to be in .wav format (or some other format)? Can I not just use an .mp3 file for that? I find it hard to believe that my old motorola razor could use mp3 files as text alerts and my ppc cannot.

2) Do the alert sounds / ringtones have to be in a specific location on the phone? I have a memory card with several mp3s on them but when I go in to assign a ringtone they don't show up in the drop-down list. I would really like to not to have to transfer them over to the phone's storage because it would take up room.

3) If you apply a specific ringtone to a contact, do you get that same ringtone if that person texts you, or do you get the default one?

and, lastly, 4) can you assign different text message alerts to different people? In other words, for my wife's contact on my phone I want a unique ringone, as well as a uniqe text message alert (so I'll know if I need to answer it sooner). But, the ringtone wouldn't be a good one to use for the text message because the ringtone is so much longer than a simple text alert.

Any help would be GREATLY appreciated.
