Hi. Ive been looking and searching for an hour about an answer to my question but havnt got much... I have a Hero locked to orange and Im fine with that, till now... cause I have to go to Sweden for the whole summer and it would be to expensive to use my OrangeHero over there (roaming). I dont know whether to unlock it, or root it, to use a swedish sim. Whats the difference? Any help would be appreciated. Thanx!
