Apple's support forums are humming with reports of iPhones gone non-responsive after their owners upgraded to version 3.1 of the firmware, and users are growing increasingly restive at Apple's steadfast denial that any bug exists. When the error occurs, the iPhone isplay appears to be functional, but does not react to any input on the touch screen or external buttons, and needs a hard power cycle and reboot before it will work again. The problem - dubbed "Coma Mode" for the phone's complete lack of interactivity when it gets in this state - has been noted sometimes when the phone has been put to sleep, sometimes when it's locked, and sometimes at completely random moments.
One user brought his 3G in for service at the Apple Store, where they promptly tried to sell him a 3GS. However, he got a mixed message from the Genius Bar tech, who gave him an interesting mix of party line and good guidance:
the official line is 'it is an un-repeatable error that can't be replicated on demand' so therefore, we don't acknowledge it as something to fix'.... but guys, I think your best bet is to roll your O/S back to the previous version if that worked better for you.
Problems that can't be easily replicated are definitely frustrating to developers, and it's understandable that companies may not want to allocate resources to chase down a problem that may not be a problem after all. However, customer perception still has dollars-and-cents value, and Apple should be cognizant of the price they pay when polls like this one start cropping up on websites:
Has anyone experienced this issue, and if so is there any consistency in when and how it appears?
