My 1st BlackBerry, Pearl 8100: How to unlock and add apps?

so i got an old pearl 8100 bb from a friend and it still works perfectly fine, was trying to add free apps from the bb page but i dont have a data plan or anything and was unable to download apps to my computer and transfer them onto my device. this is my first blackberry and was hoping to tweak it a bit add a flashlight app i saw something about a video app for it as well.
so how do i go about unloacking my device or adding apps and games? i have a few video and sound editors iWisoft and Audacity and the desktop manager and have no issues putting music, movies and images on the device but was unable to load any apps and was looking around on here but unsure as to where to find the correct info to unlock my 8100 and/or obtain free apps for it. any help would be greatly appreciated thanks :]
