I just bought a Jailbroken X and am unable to get the series 4 that I wanted as it requires iOS 12 or higher. I am forced to get the 3. Is it still a solid upgrade from the 2 (which I just shattered) or should I just get another 2? I hate that I'm spending almost as much for a 3 as I would for a 4. The 42 mm aluminum gps 3 is $359 on eBay. Is that steep? Thanks!
