I can. I tested out boht Bluetooth connection DUN and cable DUN on
Verizon's
EVDO network, using a certain device that, with some seem
editing (hint hint) would allow full bluetooth. I'd connect and then
run the mobile speed test on dslreports.com
My results were:
With Bluetooth: max out consistently at 160kb/s
Via USB Cable: reached speeds of 240-245 kb/s consistently.
Latency appeared unaffected regardless of Bluetooth or cable use.
My conclusion: Bluetooth is nice for headset use and for local transfer
of images and files from phone to phone or phone to computer, so I do
wish Verizon would uncripple OBEX. However, for straight data transfer
and DUN connectivity, bluetooth in its current implementation will not
effectively deliver the full speed of the higher data rates that can now
be achieved. You won't notice the difference with GRPS,
1xRTT or
probably even
EDGE. But with
EVDO (and presumbly
HSDPA), if you want to
DUN, you'll need to do so with a cable or suffer with the bottleneck.
The OP seems content to settle for
GPRS, and more power to him for that.
But if I'm going to tether, I'd like it to be faster than that,
especially since I know the capability is there. If I want dialup
speed, I can get it for far cheaper than $20 a month nowadays, and the
latency will likely be much improved too.
It's not so bad using the cable with the RAZR V3 anyway, considering the
phone's battery gets a charge off the USB cable when connected anyway
(and the data connection would otherwise consume battery power quickly).
At any rate, I'll stick with Verizon. For some people, not having
Bluetooth is the end of the world. I think it's an interesting
technology that was excellently conceived at the time it was developed,
but was late to being fully accepted and the standard is now showing its
age. My phone is not my laptop; my LAPTOP is my laptop, thus the true
interest I have in any data capabilities of my phone is to hook it up to
the laptop and enable 'net connectivity that way.
Besides, Verizon does permit fully sanctioned unlimited tethering, via
its blackberry devices (which is what I use now).
