The BlackBerry Developer Zone has been updated with some minor but helpful improvements. The Developer Zone now features a convenient “single sign-on” to the Issue Tracker, Developer Support Forums, file downloads and more. There is also a customized landing page based on your profile preferences. This is just a little tweak that means your landing page begins with a particular tab (theme development, web development, java development or general) open for your convenience. The update isn’t anything too ground breaking but it looks like the Developer Zone website is getting a little easier to navigate and use.
