Hi josephray_22,
Unlock codes are a code that is created for the Samsung Katalyst phone and is unique to its IMEI (serial number) usually one code is supplied, once it has been entered into the Samsung Katalyst mobile phone the phone is unlocked and able to use any simcard,,, so provide your IMEI number to your service provider and get the secret unlock code,,,,,

good luck with your fix,,,
have a nice day,,

IM not seeing an answer here but am having the same problem,

I want setup CD for usb prog motorola v3xx

After a little digging it appears that T-Mobile has intentionally disabled this ability. Nice of them eh? It looks like they want to "allow" us to use headsets or handsfree, but they don't feel we should be allowed to connect via bluetooth to our computers or to other phones. I guess we're either all potential criminal download pirates, or we'd make a major dent in T-Mobile's VAST revenue stream.

I wonder if this is mentioned in my contract. Because now I feel like cancelling early. If anybody gets a T-Mobile rep to bend and let you in on a workaround, please let me know.
