The trash.

No

Yes you can! Older iPhones on ebay such as the 5 or lower will be under a hundred dollars and for like a 3GS or 3G you can go all the way down to 15 dollars they just run earlier ios versions

Any iPhone is still usable and the older models are under your $100 maximum. I would recommend a 3GS (uses iOS 6.1.6), or a 4S (uses iOS 9.3.5) as they are the best bang for the low bucks. Some of the 5 series can be found in that price range and can run the latest iOS, but check the seller out carefully as when paying a low price for a newer iPhone, you need to be sure it will be a usable phone.
