Both networks have confirmed that they will be bringing the Curve 9360 to their customers, with a UK release date given as "coming soon".
"This exciting new BlackBerry smartphone offers a faster browsing experience as well as access to familiar favourite features we know our customers love, such as BBM, on Three's award-winning 3G network," said Sylvia Chind, head of handsets at Three.
The BlackBerry Curve 9360 is billed as an affordable smartphone for people looking to upgrade from feature phones or from older Curve models.
We have yet to be given details of what deals will be on offer, but it's unlikely to be too pricey.
The phone has a 2.4 inch screen, 5MP camera and brings the latest Blackberry OS 7 to boot.
