Vista users will be happy to know that HTC has released modem drivers for the UMTS/HSDPA capable HTC TyTN (HTC Hermes)and HTC MTeoR (HTC Breeze). If you experienced issues using either device as a broadband modem to connect your Vista PC via USB, the new drivers should make those problems a thing of the past.
Arne from the::unwired not only found these but also posted instructions on how to get everything working.
The files can be found at the HTC web site: HTC TyTN and HTC MTeoR.
