Like others, I get the annoying popup requiring me to click "YES" on the you are on an international network to use data every hour or so. But also, for some reason data on my phone has terrible reception so the cause may be that the data network is going in and out, so the popup appears every time it connects. I will have 4 bars, can make/receive calls, can sms no problem, but can't connect to the internet or get email.
In the Munich airport, I've used the Motorola Napoleon (A4500, yes that awesome phone that for some reason Moto decided not to release), the HTC Ozone, and my Droid 2 Global from the same seat in the Lufthansa lounge. All connected to data networks effortlessly except for some reason my Droid 2 refuses to do so. Data is also terrible at my workplace in Munich. I spent some time on the phone with Verizon, but basically amounted to checking boxes that I already checked in the data manager and rebooting the phone. I've also tried to select other networks (going out of automatic network selection mode) with no luck?
Does the Droid 2 Global have a problem with GSM data networks? To me this looks like a bug in the accepting of the "Yes" on the annoying popup (why else would it popup all the time if it wasn't a bug?) so there is a flag somewhere that isn't getting set. This phone is worthless to me while roaming without data.
