Symbian and Software Signing

Well, started to install some Software on my new toy. I learned, that all Software you want to install on your e71 needs to be signed by the developer of that software. If you don't pay for a certificate as a developer, the developer has to do that manually for every IMEI, which wants to install the software. How ill is that?

Btw, I am on vacation next week, so no E-Mails etc. Even if I now have a phone, which can read/send E-Mails and surf the net ;).
