Wifi with iphone help?

Right, this is totally random but here goes,My wifi in my house is WPA, pretty much all Ds games don't work with it, I have an iphone and this thing called mywi, it lets you create a wifi network from your iphone and lets you connect wifi devices to it when you have no internet connection, it works when connecting my macbook to it but when I try to connect my Dsi it gives me the error: 51300The wifi network is on channel 3 if that makes a difference, can someone please help me? :)

Your iPhone may not be compatible with the DS WiFi requirements.

Honestly it's not that bad, and if you aren't in a densely populated area and/or keep an eye on your network setup, there is no danger.
