The UIQ 2.1 SDK Update 1.0 (June 2004) is out, but I do not know if we should download it: the only important change is a .CHM help system which will run only in Windoze environments (ouch!!). Anyways, if you want to have a look, click here (free registration required): http://www.symbian.com/developer/sdks_uiq21.asp
