Helpful info on deleting icon

I had some trouble deleting a couple icons on my Blackberry. I wanted to delete a couple apps to free up some space. I did the usual options>advanced options>applications>delete routine. When it asked to reboot now or later i chose later. After turning my phone off and back on, the icon was still there but not in the applications menu. Neither was it in the service book. It was still showing that it was installed in Blackberry App World. What i did was highlight the app in MY World in Blackberry Apps. Press the main menu button. Click on View Details. Then another screen came up saying something about information stored on SD card. It asked if i wanted to reboot now or later. I rebooted and both icons were gone. Hope this helps.
