  • iPhone 3.1 "Coma Mode" Reports Mount, Apple Silent

    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.
    Fairly consistent reports show that rolling back to 3.01 resolves all "Coma" issues, a strong indication that the problem has to do with the new firmware.

    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?

      ummm.... I thought you weren't able to "roll-back" to 3.0 once you install 3.1???!
      I'm really starting to believe that I may never upgrade my 3GS from 3.0! There's no sign of a jailbreak, and now this crap??
      u can got back in the fw u didnt c the guide?
      and 3.1 can already b jailbroken

      Once iPod touch 2g 3.1 jailbreak comes out, I'll test it for myself. In the mean time, someone needs to log memory usage and stuff like that in the background (something like syslog) and figure out the problem

      Mine does this also, except it takes screen shots constantly for about a minute. Then it will finally become ressponsive again..

      That REALLY sucks. Why did Apple do this? Hope it doesn't happen to iPod touch users.

      I updated last week to a custom 3.1 (i'm on windows) and actually think my phone is more responsive and faster to open programs now. My only gripe is that I can't get cydia to load all my sources.

      OT, but I have a 3GS on 3.0.1 and bought it the day Apple stopped signing the 3.0 files.. I LOVE my 3GS's speed to death, but the fact that a jailbreak hasn't arisen yet scares me bigtime.. I couldn't believe it when I found out I couldn't even restore due to missing Saurik's window. Simply incredible.

      That's been happening to me on 3.0.1 as well for the past two or three days.

      This Happened To My iPod Yesterday But I Don't Know If Its The Same Thing Since Its On The iPod And Not The iPhone. Same Exact Issue Tho And The Hard Reboot Lagged! I Thought It Crashed. Which Would Suck After Upgrading To iTunes 9 It No Longer Works At All (iTunes In General) And I Wouldn't Be Able To Restore Or Backup. Any Advise On Either One? iPod And My iTunes Issue? Many Others Have The Same Problem On Apple Discussions, Yet They Deny Any Issue, Blaming My Computer. APPLE IS MAKING ME UNHAPPY AND I MIGHT BE CONSIDERING A ZUNE HD IN A FEW DAYS IF APPLE CANT FIX EITHER ISSUE. I REALLY CAN'T DO ANYTHING TO MY IPOD. CANT ADD NEW MUSIC, VIDEOS, BACKUP, RESTORE, ETC!!!

      Well if you want another iPhone this might be the best time to do it before hoards of people start doing it and they just start downgrading you.
