I am not capable of solving shitty downscaled image sharing; flakiness with mms message receipt (esp photos) both on tmobile and verizon; and even worse downscaled video sharing. Because those cannot be addressed by anyone but the telcos.

Nor the inability to add people to groups. sms doesn't have groups; it has pools of numbers. And it works terribly when, eg, one of you is traveling or living outside the US.

You send the photo via mms. When there's that one great shot you really want to save, ask them to email it to you. This isn't nearly as hard as you make it out to be.
