I'm actually curious on the best way to go about using all of our devices in Poland. What I want to be able to do is to: 1. Use data, no I wont be downloading movies or apps but I would like to use google maps while driving or in case I'm lost. 2. Be able to call between phones while in Poland, wont be chatting for hours but again for emergency use. The iPhone 3g is running what ever the latest iOS it can run, dont have the phone here so I cant verify but my iPhone 4 is running 5.1 and all the lastest stuff. Not too sure if the iPhone 4 is eligible for the unlock as I have a green light for upgrading but I may have to check later when the contract if any expires. So really what I'm wondering is: 1. How to go about using data without it costing a fortune. I see AT&T offers international data plans and worse comes to worse I'll buy it. I've heard of pre paid micro sim's that offer data for cheap and not too sure what I'd need to do (jailbreak, unlock, piggy back sim, etc). Thanks!
