Samsung I5510 with Froyo and physical keyboard spotted at IFA 2010This article contains unofficial information.
It looks like a mid-range UMTS Android phone with a physical slide-out QWERTY, and an average screen size. It packs decent hardware, though - a 5MP camera, Bluetooth 3.0, Wi-Fi and a microSD card slot. That brings us to the very average expected price of 200 EUR (~$256), but still no word on what other carriers will be having the Samsung I5510.
