You are certainly correct about Verizon's release of RAZR V3 units with disabled or missing Bluetooth files, but it's important to note that the release of earlier units with these profiles activated was truly an anomaly for Verizon Wireless. They have long sought to preserve the significant revenue stream from services like Get it Now, charging users for what would otherwise be 'free' file transfers. I have no idea how the initial hardware release ever got by their 'Bluetooth police!'
It's also important to note, however, that this is not a trend, and other major US carriers have not adopted this tactic. While each carrier has their unique set of annoying issues, only Verizon consistently disables or defeats the OBEX profile, and only Verizon has introduced V CAST, it's streaming technology which is—quite unfortunately—incompatible with the DUN profile, thus prohibiting users of V CAST devices from using their handset as a CDMA modem.
Cingular [once again to soon be known as AT&T,] Sprint and T-Mobile do not actively work to disable or defeat Bluetooth profiles, or introduce technologies which are incompatible with dial-up networking. T-Mobile even goes so far as to let virtually any unlocked GSM device to work on it's network, something Sprint does not do with its CDMA and iDEN handsets, and Cingular does only to a very limited extent with its GSM, but not CDMA or TDMA, handsets. Whatever the advantages—and there are many—offered by it's strong, high-speed network and advanced technologies, Verizon is the worst major US carrier when it comes to offering options to its customers. Absolutely, the worst.
