I'm not responsible for what might happen on your phone if you choose to dial any of these!
These are the codes that work on the standard phone dialler app on the Orange San Francisco, but I'm pretty sure they'll be almost identical on other models that we collectively know as "ZTE Blade". Known small differences (in texts) are down to whether the firmware expects to be running on an OLED or TFT display, and whether you've deleted seemingly unused apps like ChiperTest.apk, fcctest.apk and QcNvTest.apk. Most are prefixed with "*983*", which is "*ZTE*" in phone letters -- I've added a mnemonic for the other part where I think it's obvious (feel free to suggest better ones!).
"Automatic Inspection" runs through the basic tests automatically (usually you need press a button to move on to the next bit -- don't get thrown by any blank colour test screens!). There are a number of interesting items for developers, with hardware info and other goodies. If any of the descriptions don't make the function obvious then it's either poorly written or I don't know exactly what it does (I'll happily update this if others can explain better).
If the code has been recognised by the dialler then it will react immediately when you enter the final "#". If nothing happens when you've done that, don't press Dial!
Edit: on the ROMs based on the Japanese 2.2 you need to put the phone into "Engineering Mode" first, by dialling *ZTE*OPENEM# (*983*673636#) -- this action will be confirmed by a quick pop-up. To close this mode, dial *ZTE*CLOSEEM# (*983*2567336#) -- this then prompts whether you want to do a Factory Reset, which you do not have to do (you can simply Back away from this screen).
