Does anyome use MMS with cingular in the Orlando area?
I'm on vacation, and when I try to send an MMS, my Treo 600 tells me that it has no network setting for the current mobile operator. It was working fine in Boston, and I'm on Cingular's network in Orlando. GPRS is working fine!
I have a gateway, URL, and port specified in my MMS settings.
Can someone in Orlando share their settings so I can try them?

Thanks for any ideas,
