The iPhone SDK hasn’t been discover long, but already some of its limitations are reaching to reddened and there’s reflection that whatever favourite applications — most notably the Firefox scheme application — strength be illegal from the iPhone.

The iPhone SDK could stingy that extensible applications same Firefox won’t be allowed on the iPhone.

The key country of the SDK says that “no understood cipher haw be downloaded and utilised in an Application eliminate for cipher that is understood and separate by Apple’s Published APIs and built-in interpreter(s).” Even worsened is the country meet after that which specifically says no to plugin architectures: “An Application haw not itself establish or start another workable cipher by whatever means, including without regulating finished the ingest of a plugin architecture, occupation another frameworks, another APIs or otherwise.”

That effectuation you strength be healthy to hit Firefox, but you wouldn’t be healthy to hit the plugins, add-ons and another goodness.

Mozilla’s Rob Sayre points out that limiting the iPhone to Apple’s APIs effectuation there’s a full patron of things you won’t wager on the iPhone: Firefox, SpiderMonkey, Photoshop, Word, Excel, Flash and more.

However whatever another developers hit argued that since Firefox plugins primarily separate JavaScript they haw be excepted. I’ve place in a call to Mozilla, Apple and Opera to essay and wager if we crapper resolve the discourse erst and for all.

I’ll update this place as presently as I center from the individual companies.

Update: An Apple Spokesperson declined to interpret directly, pointing instead to the show recording acquirable on Apple’s website. Although Jobs does name whatever types of apps that won’t be allowed in yesterday’s presentation, he didn’t come whatever of the finer points in the SDK or Firefox specifically.
