A hacker known as Neimod has claimed to have "full control of the 3ds in kernel mode", allowing access beyond the 3DS's default system. When asked about the possibility of taking care of "that pesky region lock" Neimod responded that "with full kernel control anything is possible."
He stated that he does not want his hack to be used for pirated software, and so has not released information on his work, but more for potential region-free gaming on the handheld.
Region locking is a common complaint regarding video game systems. Importing was quite popular with the Nintendo DS, for games that couldn't be found in a given region, such as Tingle's Rosy Rupeeland in North America.
Could we be seeing the start of a new region-free era for the Nintendo 3DS?
