The freeze happens in the system menu's data management>sd card (happens on all sd cards I try and also does it when no sd card is inserted)Thank you for testing out
The freeze can be due to the fact that v3 may request some SD function that are not present in IOS31 but are only present in IOS61; did you try a non-SDHC card and see if the freeze persists ?
the photo channel works great!!! It just bugs the system menu VERY slightly like my custom mii channel, thanks!
i'll write more below
