I bought a refurb from eBay. Sound worked initially but then stopped altogether. Found this thread and tried pushing on speaker and sure enough it worked. As soon as I stopped pushing the sound would stop. Put it in a tight fitting case and it worked for about a week and then stopped working again although pushing on the speaker would still get it to work. Sent it in to Motorola for warranty repair (5 business day turnaround) and it's been stellar ever since. If you can't get it replaced by Verizon then Motorola will fix it for free (minus shipping) since it is still under 1-year hardware warranty.
