Well here's an interesting bit of information from Verizon. Apparently users are getting a free VZW text message informing them that the emergency call button on the Fascinate may not function when the phone is locked. This applies to the currently available SCH-i500.DL09 software build and a fix will be pushed "soon".
The message reads:
Free VZW Msg(s) – Use of your emergency call button on your Fascinate phone with software SCH-i500.DL09 may not work while the phone is locked. A software fix will be pushed to your device soon. Until available, disable pattern lock to ensure emergency calls can be placed. To check your software version press Applications>Settings>About phone and view Build number. Only version SCHi-500.DL09 is impacted by this issue. Versions SCH-i500.DI01 and SCH-i500.DH12 are functioning properly. To disable pattern lock press Applications>Settings>Location & Security and remove check from Require Pattern.
So if you have a Verizon Fascinate, it's recommended that you disable pattern lock until you receive the new update to place emergency calls. Anyone else get this message?
