How to I get ringtones from iTunes?

I know I can get it off my phone, but since i don't know my security question answers, I have to make purchases on iTunes on my laptop. Is there anyway I can purchase ringtones off iTunes on my computer and just download it to my iphone?

It's actually a very easy process, and doesn't require much time. First thing you have to do is Sync your IPhone with the Itunes on your laptop or desktop. This is automatically done when you connect your phone to the laptop using the charger cable in an IPhone charger. Depending on your Itunes software this varies. A better way to make sure is click on your IPhone's name on the sidebar of iTunes and scroll down to sync your Phone. Once this is done, simply purchase the ringtones you wanted and go back to the sidebar and scroll up until Ringtones appears. Click on this and check to make sure that your ringtones downloaded. The final step is to simply click on the ringtone and drag it straight on to the name of your phone on the sidebar. Voila! You now have the ringtones you wanted on your phone. This same process is how you do it with music and videos. Some versions of iTunes have a button on the bottom-left corner of the iTunes screen that says autofill and it will automatically do this to your phone. An easier and cheaper way to get ringtones is through jail-breaking your phone and searching for the ringtones in Cydia, hit install and when you go back to Ringtones in Sounds it'll be there.
