Nothing wrong with complaining about whatever you want to complain about, but not here - which is complaining to fellow users only. This is a user to user help forum for technical support issues and questions only.
Before purchasing an iPhone, I can count on one hand the number of times I exchanged MMS, so I couldn't care less about MMS. I would like to see cut/copy/paste and the ability to forward an SMS - although not something I need on a regular basis, but it is a complete waste of your time to complain about anything here, which won't accomplish anything.
Use this link instead - but I suggest providing your feedback to Apple in a constructive manner. If the folks who receive the feedback are anything like me, the non-constructive rants, whining, and complaints likely go straight to the garbage, and rightfully so.
