My iPhone 4 just died on me. No reason or anything. Sent a couple of mms messages, battery was at 60% and then it just went blank. No response or anything. I searched the forums and found that doing a hard reset for 30 seconds may bring it back - I tried that and it worked.
Just wondering if there is a need to be concerned about this unit?

Thank you for posting this! I went to make a call and my iPhone was just dead and blank. I tried the reboot a bunch of times but it didn't work until I held it for 30 seconds. It's back on now like nothing happened. Thanks!
