1. Sometimes when screen is locked when in portrait mode of the ipod app or any other app the lockscreen goes bizarre and needs to be respringed.
2. Still unable to send any file to ipod touch 3g and to Sony xperia x10 always the iPhone shows "transfer failed".
3. Files received via bluetooth shows "(null)" while receiving.
4. Could not add any file to iPod library

But I was able to send and receive files from PC very easily and seamlessly.
Hope to see a update soon.
