My iphone 4 is finally starting to die so I'll be in the market for a new device soon. With the new iphone being rumored to move to bigger screen sizes the iphone is now losing the main advantage it had over android to me, so I'll be considering other phones. Since I've had a couple phones get water damaged I would love to have one that is waterproof. As for the screen size I prefer smaller screen sizes so 4" or less if it has to be a bigger one then I would want one that is actually going to be big enough to use as a tablet so probably 5.5" or even a bit more. I'm ok with ones that are a bit older if they are significantly cheaper as I don't have a huge budget, but I need one that I unlocked. So any suggestions if what phone to get, and it doesn't have to be limited to android, I'm good with trying any OS.
