As of this morning i noticed that neither my speakerphone nor any of my ringtones are working!! I thought that i might have just changed the profile or one of the settings, but i could find no evidence that this had been done. I also tried a reset to see if that would fix it, but to no avail. Now i am afraid that i may have damaged the speaker somehow

Has anyone experienced this? Anyone know how to check the speaker? Is it possible to fix the speaker? I haven't yet torn into the phone to check it out, but I will most likely be doing that over the weekend.
thanks
