How unusual, I just tested and all the commands you mentioned there worked for me (running 1.1 of MoDaCo's ROM on my sprint hero).
Over at XDA, I noticed Apps2SD on this ROM is...not consistent. It appears to be working for some and not others. I haven't decided to take the plunge yet since I'm not terribly low on space.
Sorry... I rebooted after the initial boot/setup and all the ## codes work fine. Also, OTA PRL update works fine...
Plus... DroidExplorer works pretty OK (only tried it on Win7 x64 and it's a bit buggy... have to try it on my Win7 x86) with this ROM...!!!!! AWESOME JOB!!!
