Nintendo has just released a new update to the Internet Channel. This new update upgrades Flash from version 7 to Lite 3.1 (which corresponds ot Version 8). I'm guessing there are also some performance tweaks aswell.
Additionally, the Internet Channel will now be 100% free. Nintendo will also offer to those who paid 500 points for the Internet Channel a free NES Virtual Console game in October.
