My Jolla's speaker just went AWOL. Headphones work and so does the phone speaker, it's just the loudspeaker that's suddenly gone silent. Out of the blue. One moment it went beep when I plugged in the charger, the next it went quiet when an email alert was supposed to sound.

My questions are,

1. How difficult is it to open the phone? Is it just to remove TOH and unscrew those 10 screws? How high is the risk of stripping them, on the scale from 0% (N900) to 100% (N9)?
2. How is the speaker attached? Springs, solder, sellotape, magic?
3. Anhone know any source for a replacement?
