First, apologies if this exact query has been posted. I did my best to search for it, and saw some posts on when to upgrade, but not on buying a 2g vs. 3g outright. So: I'm in need of some advice on whether to buy a new legally unlocked 3g iphone (about 650-700 euros) or a lightly used, illegally unlocked 2g (around 350-400 euros). I can afford either option, BUT I don't want to pay 300 euros more if it won't be 300 euros more useful to me-- which is why I'm looking for your opinions. While I know this is somewhat a subjective matter, I would really like to hear other people's thoughts. I swap between residences in Germany and the US, and have pay-as-you-go SIMs for both countries (T-Mobile and Simyo, respectively)-- hence the need to avoid contracts. I've been using a phone that works on Edge, and don't really have any complaints about the data service in Germany (in the US it's irrelevant, as T-Mobile won't give me data with my prepay). I mostly use my phone for the calendar function, to look up the occasional address and google map on the go, check my email, and send texts. I'm also looking forward to being able to use my iPhone as a replacement for my little 3g nano. I think I'd probably be fine with the 2g iPhone, based on my usage habits. But then, perhaps what one doesn't know *can* hurt one-- to that end, I'm having a tough time figuring out whether 3g speeds and GPS would be such a magical experience that I'd pick the new iPhone in a minute, if I only knew what I were missing. Thoughts, or just a quick "2g" or "3g" appreciated.
