It would be great if people read the user guide before complaining about a "missing" feature. Page 108 of 245 in the iBook version of the iPhone user guide describes how to do what you want.
A PDF iPhone iOS 5 user guide is here. You can also download it as a free iBook.
Why are you being so rude guys ? It's not a big deal! Relax. I have other things to do than to read the iPhone 245 pages user guide... Sorry to have a life. It would be great if you could chill a little bit.
Whatever, thanks for your help Rysz.
Is the expression "it would be great to..." is not used in the USA? Because I'm french.
A simple search of the forums of the User's Guide or google could have answered the question.
We all have lives and as user's, none of us are paid to answer silly questions, we help because we want to. Asking silly questions that you could have easily found the answer to yourself becomes tedious and annoying.
Being "busy" is no excuse to be lazy. Educate yourself.
You could have respond with humility. I didn't put any judgement in my question. I like people that help each other but only in a certain way. If not, don't even do it! You don't know me so don't judge me as a lazy person. I was sure that everything was so easy and intuitive to do on an IPhone so that's why I came here directly. I was sure that this functionality didn't exist. It was a mistake but sorry I am a human, I do mistakes. Just try to be gentlemen in your answers. Sorry for the offenses but I really didn't like the way you answered guys. It's disrespect.
