In the first post it says that <4.5 should update to at least 4.5. What are the benefits of me updating the firmware of my 4.1 and 4.4 3DS consoles to 4.5? Updates that happened from 4.0 to 4.5 were nothing more than security updates that only offered the blocking of DS flashcarts. There really is no legitimate reason to update the firmware version to 4.5 since the gateway 3ds will work on firmware 4.0 - 4.5. On the other hand, the browser version might need to be updated so somebody might be able to get the homebrew browser installed, but a firmware update to 4.5 from a cart isn't going to update the browser version.
