LONG delay with MMS to/from Verizon/T-Mobile Customers

[Sifter]

I have a Blackberry 7520 on nextel, and I can send MMS outgoing to verizon or t-mobile customers, and they will get it right away. When they reply, it consistantly takes 15+ minutes to get to me, sometimes 2-4 hours. When I MMS to cingular, the send/receive is right away. Is this a nextel issue or verizon/t-mobile? Where do I start troubleshooting? Ive called nextel and told them about it, the only thing they said is that they saw some conflicts in how the MMS message was being routed, MMS/SMS, and after they made some changes, to turn my BB off, and all would be better. Anyone else seeing this delay?

I've talked with cingular twice and rim once...there are some serious(!?!) network issues all over the place...I guess...

Important to remember that MMS has no warranty on speed.
