Iphone 4? Tell me everything

If you are on a budget up to about £200 would it be a good buy to get a second hand iphone 4? I have seen a few on ebay in reasonable condition. Can you get ios 7? Can you get face time and imessage? Thanks in advance. Please if you know anything just comment thanks

No. It's not possible and iPhone 4 is not cool at all. So I say you should go for Samsung android phone

Can't comment anything on price. But iPhone 4 can run iOS 7, but it would not be a good experience like the newer devices. Yes you can get iMessage and FaceTime. Just enable both of this features in settings>Message and settings>Facetime

Its still a very capable phone.

Yes it can get iOS 7, FaceTime (1st iPhone to do that) as well as iMessage.
