When the Porsche Design P'9981 BlackBerry first came out, it was said that Harrods sold out of them pretty quickly. Harrods are anticipating the same high demand again and are making this a first come, first served process. You will not able to reserve one, neither will it be available from Harrods' online store.
I must say, the matte black version does look sexier than the original. The Porsche Design line is, of course, not for everyone but if you're in the U.K. and you're interested pop into Harrods from 10am tomorrow if you'd like one.
