For Ovi publishers creating Symbian and Java™ apps, there typically are initial investment costs such as those associated with obtaining a Publisher ID and having the apps Symbian Signed or Java Verified™. Currently, this process can take about four weeks and cost up to $215 (157 euros).
Ovi publishers can request to have certain apps signed for free by Nokia, reducing the turnaround time to two weeks and eliminating the signing costs. Qt, Symbian C++, Java™, and Adobe Flash Lite apps can be signed by Nokia.
hmm so i have to pay up to 157 € if i want to publish something that isnt QT, Symbian C++, Java or Adobe flash lite ??? What else can be published ?
Anyways as you said you had to pay only around 50€. Sounds quite ok for me.
