I am not new to Blackberry. Probably been buying Blackberry since 2000 and love the device. Just upgraded with AT & T to a new Bold 9000 and have already had to exchange it within the first 5 days. I still have a Bold, but now am experiencing the same problem. I love Blackberry so if anyone has any idea about why I keep getting a message, "radio path unavailable", please let me know. Thanks in advance. I otherwise love this device.
