How do you put an iPhone on vibrate?

I figured out an easy/hard way to make the iphone actually vibrate on incoming texts and sound on incoming calls. First, you will need to download any free ringtone maker and also a free music downloader. Then, you will need to go on the music downloader and use its browser to search on google.In google search silent mp3 ringtone 2 sec and click on the third url from the top. Then, download the silent, 5 second, ringtone and connect your iphone to the computer. Next, you have to drag and drop from the apps section on your phone, on iTunes into your music from the music downloader app. After that, you can now use the ringtone maker app to make the mp3 into a ringtone. Next, follow the steps from the app to make it into a ringtone and set vibrate on and the silent ringtone on and you will then be able to have only vibrate on texts, and ring on calls, without having to toggle the switch on the left side of the phone.
