So I recently discovered a custom firmware for old iPhones based on whatever the last version of iOS they were able to use, it's called Whited00r. In the case of this iPhone 2G I got on ebay for $35, it's iOS 3.1.3. It's designed to look like iOS 7 and mimic as much of its functionality as it possibly can. It even has it's own App Store where you can download old versions of apps that will work with iOS 3 since Apple's "Last Compatible Version" works with iOS 4 at minimum. I was able to find a good SIM adapter thanks to this forum that doesn't damage the SIM reader inside the iPhone and I put my nano-sim into the iPhone. It activated right up. Not sure how long I will attempt to actually use this, but it was a pretty fun little project and the iPhone is in great shape and will be fun to show to future generations one day. I even have the original box and everything. It's crazy how I was so amazed by this phone back in 2007 (I had one but it broke a few years ago, that's why I got one off ebay) and felt like it couldn't possibly get any better. I mean, what else could you need, right? Would you ever be able to use an original iPhone as your daily driver today?
