Sony Ericsson K750i/W800i... The Perfect PSP Companion!
These phones have the same memory stick slot as the PSP. You can use the phone to move files around and listen to your PSP music’s and watch supported videos. You can even take pictures on the phone and view them on your PSP’s beautiful screen, and use your phone’s web browser to download files when you’re away from Wi-Fi Hotspots.
Is this a match made in heaven? :) The W800i should be out in the US within a few weeks. No plans to release the K750i here in the States right now, but you can import them from Europe through eBay and the like.
