**The title of the thread should read 2.3.3** Have an LG Shine Plus c710h on Telus network. Did the 2.3.3 upgrade and once yesterday and TWICE today from an unplugged idle state with the screen off I go to use the phone and the screen wont turn on. All the buttons light up but cant get nothing on the screen. Only way to get the screen back is to remove/replace the battery. I thought battery pulls were a Blackberry thing. Anyone else having this problem since the upgrade or know of a possible solution to this issue?
