Since my Samsung phone conked out, I would like to give Apple a chance (please no comments like "uh Apple is stupid, buy yourself an xy!"). I just got from a friend the page Clever Tronic recommended, where you can buy cheap mobile phones and so on. I have discovered an iPhone 5S, which was new, but the package is opened, thus it costs € 499 instead of € 600 estimated.
I wanted now times generally ask how that is with the guarantee and warranty from Apple if you have his phone as not ordered from Media Markt but precisely from an online store.
In Clever Tronic reads "24 months warranty", what exactly does that mean and then I can simply register with Apple, when my cell phone for example has a technical defect?
PS: The friend who recommended me, I can not ask because he is currently on vacation.
I appreciate your answers!
