I wonder if the fact that it is creating a slide show is why AT&T can not currently receive an MMS from my phone? I am sending scaled down images of 1k, 7k, etc so it isn't the usual size limitation of MMS.
The 'only' way I can currently get an MMS to AT&T is use the stock HTC Sense Messaging app, attach a picture, have it scale first, then edit the image (slide show really) and add text.
Unfortunately, I do not have phones on other networks to test MMS to. I also do not know anyone else on Verizon to test this with. I do know that from my phone I can not send MMS from Verizon to AT&T.
