Okay, we still had problems with the handheld itself and decided to wipe the handheld.
I read thru a few articles on the JL_cmder software and felt this was a doable solution.
I downloaded the newest handheld BB software from Nextel/BB's site and then wiped the device.
Upon trying to install the OS, I receive an error:
UNABLE TO COMPLETE THE LOADING OPERATION:
A fatal error has occurred while updating your device's software. Please try again.
Unable to communicate with the radio hardware. Please ensure that a charged battery is installed in the device and try the loading operation again. [P:0x0000000F]
It does this right after it erases the handheld and loads the software, re-initializes it and then attempts to communicate with the radio software.
I have the 507 Error as well...
