Well, I finally had the opportunity (if you can call it that ) to use the Pro outside the US. Spent the week traveling about the UK and EU, so I now have an opinion as to how it performs. First of all, the battery usage when running on pure GSM is AWFUL. At home with the regular battery, and only the CDMA radio on (No gps, no bluetooth or any other radios), I can usually get an entire day with no problem. With GSM only, I got barely 6 hours every day over 7 days. It was awful. I had a dead battery all the time. I finally bought the extended battery when I got back home....... Voice mail was flaky for sure. I despise voice mail in general, but when I touched down at JFK, like 20 of them appeared. This may be a broader flakiness of verizon VM notifications not making through the networks in europe, .... who knows. Exchange was fine, although my personal IMAP mail was flaky. There were a bunch missing from my personal IMAP account. Texting was fine (as you would expect) Voice was terrific, clear and crisp. Can't wait to get my $5000 bill from VZW for the calls :icon_ banana: I was gonna get a cheapo SIM card, but was so busy in meetings, airports and trains, that I never got to pick one up. Overall, I was pretty pleased with it. Next time, I'll have the extended battery, and may in fact get a second one. My big take away was that it is a really good global phone (as far as Verizon goes at least) and worked pretty well. Also, that GSM only simply DRINKS battery power.
