Last August we got our first look at Siemens’ SK65, a business-focused smartphone. At that time it was innovative, incorporating RIM's BlackBerry email solution and a unique twist-out keyboard. It took until February this year for Siemens to formally introduce the product, and it's now available from Vodafone, O2, T-Mobile and BT Mobile. It says something for Siemens' foresight that both the BlackBerry and keyboard features remain compelling in theory. Now we get to see how they work in practice.
