Of what I know, you still need to be on a firmware version between 2.0 and 9.2. If the 3DS doesn't have the internet browser, you should upgrade to 4.x (MSET exploit).

little to no risk for 3rd party games, but 1st party (Nintendo published) games frequently have multiple revisions with higher firmware than listed on 3dsdb. (and they're more expensive usually!)
