I have a Droid 2 Global and it suddenly hit me that, as I have not traveled out of the country since I got the phone, I have a sim card. My question now is that I've been having a lot of issues with the phone lately (I'm on replacement D2G number 3), so I was wondering if it would be possible to buy an unlocked phone from another country or even here and stick the sim card in that phone. Would it work or would I have to do something else, or is it not even possible? Thanks for any input. BTW, I'm fairly technology savvy, but not when it comes to phones, so go easy on me =). Also, just wanted to say hi to everyone, and thanks for a lot of the information I've found here.
