The handset by Nokia’s luxury unit features premium materials including a Titanium chassis, cowhide leather back, scratch-resistant sapphire crystal face and polished ceramic.It’s not all flash, fortunately. One of the unique features in the Ascent Ti is the Vertu Fortress technology. This synchronizes important data on the phone such as contact details, calendar and notes to a remote server, (supposedly) maintained in an ex-military bunker at a secure location in the English countryside. So if you do lose your very expensive phone, at least the data can be quickly restored in a new handset, providing some peace of mind.
