Got official update to 3.0 onto my phone this morning via iTunes.  Had already installed the ipcc carrier bundle succesfully under 2.2.1.

Happy to report that tethering and voicemail continue to work fine as does internet browsing on the phone itself.

MMS is the problem:

I have two iPhones set up as above.  One will send MMS, but they are received as SMS with weblinks on another iPhone.  The other iPhone (the one that receives MMS as weblinks) won't send MMS - they hang and get the exclamation mark as unsent.

QUESTIONS:

1 - has anyone been able to both send and receive MMS on their iPhone over XT?

2 - could it be something on the XT network side rather than on the handset causing this issue?

MAny thanks.
