I've been travelling with just my Blackberry and have experienced no issues getting handheld broadband/email/etc on GSM networks in Europe.
However, I recently had to carry my laptop with me and was surprised that I could not use my BB as a tethered modem... the access call it was making was US-only.
I tried Verizon support and they didn't seem to understand the question.
Before I travel again, I'd like to have this sorted... how do I get tethered broadband in Europe? it would seem pretty simple since it's obvious the BB itself is getting it...
Thanks!
Bill
