I’m really glad I’m not paying for Apple’s bandwidth bill this month: the company today announced that the recently-released iPhone SDK has been downloaded a massive 100,000 times already.  That’s 210TB in just four days!  The package contains all the APIs, tools and testing software necessary to create third-party apps for the iPhone, although it won’t be until June that they can be officially loaded onto the cellphone itself.

“Developer reaction to the iPhone SDK has been incredible with more than 100,000 downloads in the first four days.  Also, over one million people have watched the launch video on Apple.com, further demonstrating the incredible interest developers have in creating applications for the iPhone” Philip Schiller, senior vice president of Worldwide Product Marketing, Apple

Currently sign-ups to the iPhone Developer Program - membership of which is necessary if developers want to release their software - is limited to the US, but Apple are promising further availability over the coming months.  Their press release also included a bevy of glowing soundbites from companies like Sega, Six Apart and more, confirming that Pac Man, Galaga, NetSuite SuitePhone, Bejeweled, Zuma, Peggle and a TypePad application are all in development.
