Hi, I finally convince my dad to get an iphone after I had a great experience with it. He's not into technology that much, meaning he doesn't care if he get the latest tech. So I'm deciding between iphone 3g refurbish ($50) and 3gs ($199). He'll use this mainly for internet, emails, maps, and probably some business apps. My concern is, will there be any advanced apps in the future that is only for 3gs? Also is it worth getting a 3gs for an old guy who doesn't do hardcore gaming and stuff, he'll just do the basic stuff. In overall, imagine a guy in his 50s, not a tech person, and would mainly use the phone for emails and internet and business (he's a businessman). Is it worth to get the refurbished 3g for $50 or the 3gs for $199? It would be nice to save some money. What do you guys think?
