This seems strange. I understand not volunteering the info, but if someone asks I don't see a problem with letting them know. You may not be asking for PR but you can always use it.

See below.

okay, it's clearly not about PR - you haven't mentioned the name yet. but i'm still very curious, and at this point i don't think it would distract from the intention of this post.

Actually, the real reason I don't want to tell the app is that it's linked to my name rather obviously, and I don't want people to know that I was that broke.

ah, okay - that's fair enough. the real reason i'm curious is that i want to quit my job and publish my own software.

would you be comfortable telling us what category the app falls into, or giving a sense of what it does? can you say what kind of marketing went into attaining those sales?

I can tell you something - absolutely do not quit your job till you are making $3000 in sales. The Apple iTunes store is a very very fickle baby. It's like a wild horse that is always bucking and trying to throw you off, and to stay on you keep having to think faster and anticipate its moves.

No matter how great your idea is, the Apple store will be unforgiving as hell. There is a LOT to be learned, and while you are learning it, you will need to have a job, because something needs to pay for the mistakes.

Wrong.

Do not quit your day job until you have BEEN PAID $3000 in the bank. Until you can go to the ATM and take out some of that $3000.

Have you not learned anything from this experience?
