The world's first 3D smartphone is landing in the UK on 7 July, and to be more specific it's landing exclusively at the Carphone Warehouse and Best Buy.

The handset dealer has revealed that pre-orders for the Froyo (Gingerbread should be coming soon) device have opened and that it will be available free of charge on a £35 per month contract.

The LG Optimus 3D was announced to much fanfare at Mobile World Congress in February. The 3D element, which can be switched off, is possible thanks to a glasses-free 4.3-inch screen.

It is able to power its 3D capabilities with a powerful 1GHz dual-core, dual-channel Texas Instruments OMAP4 processor, and display it all on a WVGA screen. It also packs 8GB of memory and 4GB LP DDR2, with a 1,500mAh battery on board too.

Phones 4u had previously told Pocket-lint that it too will be stocking the Optimus 3D, and will even be offering an exclusive white version as well.
