Looks very good, I think I have nice use case for my "broken" camera modules.

BTW, oddly enough, my module refused to focus on objects further away than ~14 cm after only removing it from N900's mainboard, not after disassembling it (I've disassembled it later, when I knew, that I had nothing to loose). In fact, even when adjusting manually, I can not get it to focus further away.

IDK if it's the same in Your case, maybe not. While reading through pages about modifying cameras for IR, I've found information, that replacing IR filter with non filtering glass is required to keep autofocus working - it may be related to Your problems.

Best way to check it, is to use fcam or CSSU'ish camera application - use manual focus, and see, if You can get sharp view on far away objects. It would be very useful to know.
