Problem Eclipse 3.5 With Blackberry Plugin

I Have experienced, when using eclipse 3.5(Galileo)  
Something similiar like this
"Cannot complete the install because of a conflicting dependency.
  Software being installed: BlackBerry Web Development Plug-in 1.0.0.200907241249-33 (net.rim.browser.tools.feature.feature.group 1.0.0.200907241249-33)

  Only one of the following can be installed at once:
    OSGi System Bundle 3.4.3.R34x_v20081215-1030 (org.eclipse.osgi 3.4.3.R34x_v20081215-1030)

So the solution was just using the older version of eclipse 3.4(Ganymede), and keep in mind that you can safely install multiple versions of Eclipse into separate directories on your computer.

Hope this post was useful ! ^^
