iPhone 1g 2g or 3g......?????
I do not know for sure. When I had the first iPhone, it worked just fine. I now have the 3G iPhone and it works just as good.
I think you may have trouble locating an older gen iPhone,,, but maybe not. I really haven’t been keeping track of the availability.
Best of luck with it.
By the way, I was running 4 Pangolin.NET systems connected (hardwired to my laptop) and the iPhone connected to the same laptop thru the built in wifi. I was running a show, took a phone call in the middle and then returned without inturaption! then I send a text msg just cuz. Fun!
