OMJ,
Thanks for keeping my Diamond running nice and smoothly these past few months, unfortunately my Nexus One arrived a few days ago and I have been a bit preoccupied...
If anyone is with Bell (Canada eh!) and having mms issues these settings worked for me:
APN1
Name - Bell
APN - pda.bell.ca
Proxy - web.wireless.bell.ca
Port - 80
MCC - 302
MNC - 610
APN Type - default
APN2
Name - Bell MMS
APN - pda2.bell.ca
MMSC -
http://mms.bell.ca/mms/wapenc
MMS Proxy - web.wireless.bell.ca
MMC Port - 80
MCC - 302
MNC - 610
APN Type - mms
Best of luck to the current diamond users and thanks again!
