I just wanted to post this here as well so I could get more people's info and feedback. Are other people having this problem?
I just spent two hours on the phone with Verizon Customer support as well. It is the weirdest thing.
CAN send to AT&T iPhone
CAN send to Verizon Droid
CAN send to Verizon LG (old phone)
CAN send to the Customer Service Persons's Verizon Black Berry
But what started this off is:
CAN'T send to friend's Verizon Blackberry Curve
CAN'T send to friend's Verizon Blackberry 8330
CAN'T send to friend's Verizon Blackberry 8703
CAN'T send to friend's Verizon LG Versa
when attempting to send to those phones I get the error messge "you have entered an invalid address".
All of those phones are in the same area code (my local one) and I have sent mms picture messages to all of those numbers previously with my old Palm Treo 700wx on the same Verizon plan.
I'm also able to receive picture messages from the phones which I CANNOT send to.
Hope this offers more details to Motorla. The verizon customer support tech had mentioned that motorola had a planned software push for December 11 which mentioned mms support. She couldn't be more detailed about this but I'm hoping Motorola could confirm this.
