I too operate a sole proprietorship, and don't wish to incorporate. (Incorporating would give me more problems than advantages.)

I'm not sure if I'll be publishing apps on the commercial N900 store, but I've got some interesting apps in mind so perhaps.

If what you encountered was just some form that required you to enter your company details, I'd put it down to immaturity - so many aspects of the N900 / Ovi stuff for N900 seem to be undergoing rapid change, giving an impression of not even beta quality at this stage. I'd put it down to oversight.

But to have your account cancelled, that's quite different and more serious.

If they won't reinstate your account, I sure hope you get your 50 Euros back.

Maybe they really don't accept non-incorporated publishers as a matter of policy. There may be a cultural change still needed over at Ovi... Let's face it, Ovi's connected with Symbian, and Symbian isn't exactly a big open welcome-to-everyone space on the publishing side.

In which case, if they don't change soon, they'll probably find themselves competing against an alternative app store...
