Apple senior software engineer Greg Christie has revealed a number of details about the birth of the iPhone to the Wall Street Journal. Christie and his team were struggling with the original iPhone’s software when Apple co-founder and then-CEO Steve Jobs told the group it had two weeks to figure it out, or it would lose the project to another team. Needless to say, the “shockingly small” team pulled through, creating features such as slide to unlock and placing calls from the phone’s address book. Christie was made available ahead of next Monday’s latest patent trial between Apple and Samsung — one patent Apple claims Samsung infringed upon is the slide to unlock feature. Among other details included in the article is a photo revealing a messy system used by Apple to test early iPhone software.
