Father-in-law will be coming here from Finland for a month (not sure his network over there). He wants to bring his iPhone 4s over here and use it in US. Am I thinking too simply to assume he can get a prepaid card/microsim here in the US? Or is he likely to run into unlock issues/etc. If someone can point me in the right direction for info, much appreciation. Everything I've found so far is going the other way (US --> Int'l) Thanks for input.
