fwd txt reject call snooze reminders iPhone

after several months of having my iphone, and it breaking, I went in to the apple store to speak to an iPhone Genius. The name of his job title, aside from being very arrogant, was far from the truth!!
Anyway, he couldnt answer my questions, and suggested i should post them to apple. The iphone either lacks a lot of features which even my first Nokia had, or i just cant find them. Wonder if anyone can help:
Forwarding Texts:
cant forward a text. This is annoying, as if someone sends me some info in a text i wish to send on, i cant see how to forward, nor how to copy and paste the info into a new txt.
Red Button:
Wheres the reject call button? If my phone is on the lock screen when it rings, the only option I have is to answer or silence it. Silencing the ringing is no good, as people often hang up before Voicemail kicks in.
Snoozing Reminders:
if i have a calendar reminder, cant see how you snooze it. Missed loads of appointments and reminders with this one. Very easy to loose the reminders from the screen, and then not see them.
There are so many more things that thoroughly disappoint me about this phone - the bluetooth stack, the 3G/GSM implementation, cant change the home screen background from black, cant have your own ringtones - or even set a MP3 song which you have bought on itunes as a ring tone, etc etc.
However, these are more annoyances than show stoppers.
I hope someone can help with the top three above, or maybe, someone in apple might see this post and suggest to include these rudimentary features that have been present in phones since mobiles went digital in the next software release. Or maybe someone knows a way around these annoyances to make the phone usable, for me, at least.
