blkberry option, blkberry 8800, and tethering?

[greenblood]

I see some blkberry models have bt DUN, and I also see some users tethers with blkberry device + option
I may consider to go this path
but the question is: does T-Mobile allow tether with bb option/plan like Internet I currently use?
and, I use a huge amount of data due to slingbox streaming, does bb option has data cap?

There is no data cap on the unlimited data plan. You can either tether with the usb or bluetooth. However, the USB is a lot more reliable.

yup the BB add-on is truely unlimited. unlike all the other carriers.

aye... t-mo CSRs will even walk you through the tethering if you are having issues. unlimited is truly unlimited. i heard that another carrier (which resulted from a recent merger) charges $70/mo for a tethering plan. eeek!
