-- Posted by BritchesAndHose at 10:11 pm on July 3, 2009 i've made ringtones, downloaded them on my pc and sent them to my phone plenty of times. but i have new phone and sim card and every time i try to bluetooth the ringtone from my pc, it says 'invalid argument was supplied' i don't know what that means. the computer detected my phone, but it can't send the ringtone. is my phone or pc the issue? -- Posted by BritchesAndHose at 10:13 pm on July 3, 2009 if it helps, my phone can't detect my pc, but i don't think i ever had to do this with my old phone. -- Posted by hI jAMES at 2:31 am on July 4, 2009 Chances are there is something wrong with the settings.  Check the Bluetooth settings on your phone and make sure things look right.  Go to the settings of your phone and make sure the bluetooth is turned on.  Also, depending on your phone, you may have to do other steps to ensure the connection is there. After reading your second post, it makes sense to why you can't transfer files. If your phone has not discovered your pc, then it's not a paired connection. They have to be connected to each other. To be of more assistant, I must know what type of phone you're using.
