I have had difficulty sending and receiving any mms in iPhone 4, iOS 4.x. Sometimes they come through.
Just upgraded to ios5, now I can't send or receive any mms, tried others w iPhone 4 (voda), Samsung galaxy (telecom) and iPhone 3G (voda) with no dice.
Can't try sending one to myself because it iMessages it.
Not cool!
My network settings are all the default ones that come up when I reset network settings. Have no issues texting, using 3G or tethering.
Pointers?
