The Sony Ericsson P800 UIQ SDK is now available for free download from the mobility world website here. But it seems that the emulator will only be able to run C++ applications when the Code Warrior software is also present.
Eldar Murtazin of Mobile Review has just run an excellent three part review of the SonyEricsson P800. If you haven't been following the reviews as they have been posted here, then go check them out (or read them from these links; Part 1, Part 2, Part 3). They include lots of screenshots and details of the applications that come with it. Many thanks to Eldar for posting links to these reviews at AAER6!
It looks like the furore over the charges for the P800 SDK may be having an effect. According to The Register in this article a version of the UIQ SDK will be made available for free. This version will not inlcude the Metrowerks RAD IDE program, and is most beneficial to Linux users (thought the Gnupoc project).
Sony Ericsson have launched a developer competition which they are calling the P800 Application Proclamation. Sony Ericsson in conjunction with Metrowerks and Handango are aiming to encourage developers to develop using Metrowerks software innovative and cutting edge applications for the launch of the P800.
