I can send files from my MacBook to my phone, but when I try to send from my phone to my MacBook, it says "Bluetooth connection failed". I thought the problem was my phone, but I tried with my sister's phone and the same problem. I also tried my phone on her MacBook (which was an exact same model) and no problem. I've also tried re-pairing and it didn't work. So is this a hardware problem or something that can be tweaked within the system? Any suggestion? I'm using Leopard 10.5.8.
