The iPhone 6s I bought on eBay is toast. I upgraded it to iOS 11.2 and now it is a brick. I'm hoping PayPal will do the right thing and issue me a refund. So, in desperate need of a phone, I picked up a refurbished 4s for $75 bucks. After having a 6s for a month or so, now going back to a 4s, I really don't think I need another phone. I really like the tiny size and to be honest, it does everything I need a phone to do. If it conks out, for around 70 bucks I'll just buy another. Great little phone.
