I actively use a #4 (the Samsung Freeform 5) as my main phone. It supports calling and texting, but that's about it. Works decently for its purpose but you have to remember that you lose the ability to view emojis and read group chats on a dumbphone, plus the web is slower than molasses and you have to send a text if you wanna tweet with it. I don't recommend this and I'm getting supplies to upgrade to an iPhone 4.
