An iPod acting like an iPhone?

Hi everyone.
Recently my my brother bought some songs, I just found out when the bill came in that he had, I had no problem with this as he could just pay me, However there was an item that was purchased 3 times and it was a ringtone which he should not have been able to buy since he was using an iPod touch, is this possible on the iPod touch?
Thanks in advanced
P.S: the ringtone was dance with me tonight by Olly murs

It is very much possible to buy something from Apple for which you have no hardware. I once downloaded the iPad free version of Angry Birds even though I've never had an iPad. This is especially possible through iTunes (on the computer). As far as I know (being the owner of an iPod touch), it is not possible to access ringtones FROM the iPod.

Hope it helps!
