Because of the company’s restrictive non-disclosure agreement (NDA), iPhone developers are legally banned from sharing programming tips, discussing code or asking questions of one another in forums or over e-mail.
They feel as if they’re coding with their hands tied, and the frustration is enough to make iPhone programmers want to curse loudly in the direction of Cupertino."
