It seems like we can't get through a single month these days without one UK carrier or another launching an own-brand device. And, since the last device bearing a network provider's name came from Vodafone, it's only fitting that its own-brand nemesis EE gets to make the next announcement. So, without further ado, let's take a gander at the EE Rook, the carrier's newest home-grown handset aimed specifically at pay-as-you-go (PAYG) punters. Launched today for £49 for new customers and £39 for existing ones, EE calls it "the UK's lowest priced 4G smartphone." Technically, that epithet's correct, though it's only a lone pound cheaper than Vodafone's Smart 4 Turbo on PAYG. As EE's Harrier Mini is available for free on the provider's lowest-price contracts, it makes sense that the Rook be a PAYG-only affair, but what exactly do you get for that kind of money?
