Can't log in with my old Apple ID
A few days ago I bought secondhand iPhone 4. I wanted to avtivate an iCloud account but it showed me an error message "maximum number of free accounts have been activated on this iphone' okay then I wanted to long in with my old Apple ID because I had an iPhone a year ago... but it shows up the same message. Is there any way to solve this problem? I saw that people can log in with old Apple IDs but why can't I? Anyway, I logged with the old ID on AppStore.
btw, sorry for my english, I'm from poland ;D
iPhone 4, iOS 7.1.2, black, 8GB
