So, standard practice, if you don't want a fine from the data protection police... If you sell or pass on a device, it has to be wiped. Where is the problem here?
You what? Selling the device or giving it to charity is not a valid reason for erasing it, before it leaves your possession? What planet is the senior counsel coming from? And if the data is on the cloud, where is the problem?
And I must admit, I've never bothered taking SMS conversations from one device to another - or backing them up, before I've done a factory reset on a phone that has been causing problems. Email, contacts etc. are all in the cloud and transferred to the new device in a couple of minutes after it has been set up.
I can't comment on the rest of the case, as I don't know anything about sporting contracts and fees, but the claim that he wiped his devices before selling them being a bad thing is completely bogus. Oh, and I generally buy a new phone ever year or 18 months and I wipe the old one before I pass it on.
Until this article, I'd never heard of him.
