I received the newer packaging with DSi(XL) in the corner, both tested with Akio 1.8.6a and the counterfeit codes work (for whatever they are worth). If there are any other tests for their authenticity then let me know and i'll gladly test these.
Ordered two 2i from Lightake on 9th March
Shipped 11th March
Arrived today 18th March
Pretty quick to the UK, these are the newer branded DSi(XL) boxed ones
