We are planning a trip to Europe, and I was wondering if it's a good idea to unlock the Infuse to use with a European SIM card while there. Are there any problems with the phone updating or connecting to the ATT network if it's been unlocked? Is it possible to use the Infuse as a hotspot there if I have a data SIM card from there? (I haven't used it as a hotspot here, because I don't want to give up my unlimited data plan.) We're going to Germany and Austria, so any advice you have will be very welcome. I'll need Internet access for my computer while floating down the Danube - with no wifi on the boat.
