My phone's speaker stopped working yesterday...ran the diagnostic test *#0*# and tried the speaker function and no sound played. Today, just as I was getting ready to exchange my phone, the speaker began to function properly again.

Has anyone had a similar problem with their skyrocket?

One of a few oddities..
Did you happen to try a reboot? To my experiences, Android loves me more when I reboot it every now and then.
Edit: Removing the battery also does troubleshooting, as odd as that may be.
