iPhone 4 speaker working intermittently

[potdog]

Got my iphone 4 2 weeks ago, everything running perfectly until tonight. While i was listening to a podcast on speakers it suddenly went silent then a few seconds later went back to normal again. Now, the speakers is just intermittently working.

-audio okay using headset
-jailbroken


any ideas? im thinking it has something to do with the hardware, i tried restarting and it still doesn't work.

thanks!

Restore as new and if it still does it take it in to apple to replace the phone.
