iPhone Keyboard

I'm definatly a texter, i absolutly hate ringing people up, i'd much rather send a e-mail, text, tweet, i usually end up stuttering when i'm ringing someone i don't know, i also hate answering the phone... if it's someone i know i'm fine... It does annoy me sometimes that you have to have so many minutes per month, i currently have 600 minutes and have used 100... texts on the other hand, i occasionally used up the 500 i had on my last contract... now i have unlimited, now just need to get the minutes down and the data up...
