Want to learn how to develop for the iOS platform or pick up some advanced coding techniques without having to spend big bucks on a tech conference? Apple has released over 100 technical session videos from the Worldwide Developers Conference (WWDC) 2010, all free for you to download and watch at your leisure.

Apple-centric blog AppleInsider reports that in previous years, consumers that did not attend Apple's WWDC were charged $500 to download and watch the session videos.

This year, users can simply sign up for a free developer account and download the videos from Apple iTunes' iTunes U section in either HD or standard definition.

Developers interested in creating applications for Google's Android or Chrome OS can head to http://developer.android.com/videos/index.html#v=opZ69P-0Jbc or http://www.chromium.org/devtools to watch informative videos about developing for Google's platforms.
