Convenience keys located on sides of phone (in portrait view--lower right & upper left). Options > screen/keyboard > right/left side convenience key opens > select. Anyways penguin did u get a replacement after all?
i don't think you can set it to lock button with the lite version? I checked in the options, not there, only autolock on startup and autolock after dim.
and i ended up getting a new berry, rice didn't work unfortunately, kept it in for like 3 or 4 days, thanks for the advice tho, much appreciated
