The Future of Symbian
S3D writes "On 18 May 2004, Symbian, owner of the OS for high-end smartphones announced the formal launch of the Symbian Signed initiative for digitally signing and certifying Symbian applications that meet a set of test criteria. Gartner believes that Symbian Signed, in its current form, is a weak certification program oriented largely toward the needs of application publishers and network operators and may be inconvinient for developers. "
I think that I have heard this before...let me think...I'll get it...Microsoft Driver Signing. The point of that was to scare new users into buying alternate forms of hardware which have been produced by a manufacturer paid by Microsoft. While this isn't quite the same, it is restrictive to independant developers.
