I have just got an unlocked blackberry tour 9630 from US(Sprint). Its going welle for entire GSM netwotk (have't tried for CDMA). The only issue that I am getting is I can't send or receive the files via the Bluetooth functionality. I can pair the device but when transferring the files, the error message is occurring as "Connection cannot be established". When sending from different one phone message is "Device does not support a suitable service to perform this operation".. Can someone suggest me how to fix this very problem..
