Yes, I saw on Gizmodo, you can't change the ringtones. And it sucks.

Bluetooth is only for calling. Here is a list :
• It can't transfer files to a PC, or appear on a desktop for drag-and-drop file juggling.
• It can't send a photo to a Bluetooth printer.
• It can't stream audio via Bluetooth to a compatible speaker system or headset. (Video is out of the question.)
