I know the 3ds has to be at or below 4.5 to be able to run it. I currently about to purchase a 3ds with the version 4.1.0-8u. I was wondering if the "-8u" meant anything. I just want to make sure it works with the gateway 3ds since i'm about to purchase from him. While I was looking around for a gateway, I found out most sites are out of stock and people are having trouble with their shipping. After some browsing, I saw modchipsdirect.com to have stock for US customers only. I was wondering if any of you have found this site trustworthy since they don't allow paypal. I would also like to ask are there other sites that sell gateway with paypal. I really don't mind if the price is mark up 20-30% because of it.
