Anyone know how to add text tones that are less than 2-3 seconds long? I hate the available text tones the iPhone currently has (sorry but they sound like a 5 year old made them!). Anyway, I found some nice ones online but when I add them to my phone (via synching), they don't show up on my phone. I can see the ones that are longer though. Any ideas around how I can add the shorter ones? That's in advance!
