What is Einstein temperature? I know how to calculate it but I don't understard what it means...

Roughly speaking, it's the temperature below which quantum effects play a role in the statistics. Much above the Einstein temperature of a solid the Dulong-Petit law gives a good approximation of the heat capacity, but below that temperature and the heat capacity drops off and deviates significantly from Dulong-Petit.
