Rooted? Geez, i dunno. I took my S2 to a mobile dealer that is frequented by people of middle east descent. I figured they would know more about international travel than the skinny [white] guys that work in the Bell store. I told them I wanted to take it to the US, UK, and Ireland and asked them what to do. "Oh," they said. "You need to unlock your phone and buy a SIM card when you get there." I didn't know what unlocking was. And I didnt know much about SIM cards. They explained (and I googled) that it was perfectly legal. Bell would do it for $50; they did it for $30 (cash). Another customer in the store -- normal looking middle aged white guy -- told me that he buys local SIM cards wherever he travels. Done and done.
