I'm on a Desire with an SLCD too, radio is different: 32.48.00.32U_5.11.05.14, and not using same relase as you: i'm just using the 'official' release, with english language pack 3b flashed over it.
I do not have any camera issues.
Just wondering, the first version of MIUI i tried was the version before the current one: 0.11.5
On installation i did a complete wipe & clean to prevent any complications, but i was wondering if this is still needed when updating my MIUI ROM to a newer version?
