To all MMS b***chers:
For starters, MMS IS an outdated technology. It's not like the gasoline infrastructure, it can be changed due to the short lifecycle of phones in general and the switch to smartphones instead of the crap free phones any carrier will give you for signing a two-year contract.
Nevertheless, if you and/or your friends choose to use outdated nonconforming technology, I found some info you might find useful. I've used the Verizon one, but haven't tested the others.
Now, can we all get on with our email-driven lives?
Your post spectacularly fails to notice that SMS messaging is even older and more 'outdated' than MMS. Somehow it's OK for people to want to do the former, but not the latter?
Let's strip the iPhone of all 'outdated' technology. SMS and MMS are soooo old, so lets get shot of them first. Calling people using anything other than voip is positively archaic, so let's get rid of the telephony. The iPhone camera was 2 years out of date when the device was released in 2007, so now it's well over the hill, so remove it.
So what do we have left after we've got rid of all the 'outdated' technology? A pretty hollow device.
Moral of the story - old/outdated technology can still be relevant even in this date and age.
