Guarantee is required by law and is 2 years. Here the seller has rectify any deficiencies in this time or to replace it. After 6 months, however, the burden of proof will be held, which the buyer usually can not prove (perhaps no more than about an appraiser).
Guarantee is a voluntary goodwill service of the manufacturer. Furthermore, warranty does not guarantee equal. The scope of the guarantee is determined by the manufacturer itself and often different things are excluded, what it is worth as a rule to consider before buying. Apple includes, for example water damage (here are installed in the mobile phone for example, test strips that detect when the phone is in contact with water had).
Apple are innately 1 year warranty - with AppleCare it can be extended to 2 years. Only Bedinung: AppleCare must be purchased and registered within the first year of the product. I had also a warranty case and my iPhone was 24 later collected and exchanged directly with a new - super service.
Disadvantage: this warranty extension has its price ...
