I was just curious about the speed of bluetooth to my mobile phone. I noticed that after upgrading to version 8 i did not notice high transfer speeds compared to the images in 'information'. i have device number XH1351 and upgraded to the version 8. Is there a way i can increase the transfer rate or is it limited by the device. I have had no trouble transfering at all with version 8 but it takes a while sometimes with large files (100mb etc) and i just want to speed it up.....
