Sound cuts out after an incoming call

[neko]

PL goes silent after a call is received in the middle of the game. I'll need to log out and then force-quit the app (double-tap the Home button and then close the PL app) before it's restored. Has this happened to anyone else with an iPhone 4?

Happens to me on my 3GS. I think it is probably standard happening on the various iPhones. Minor annoyance, but only takes about 20 seconds to fix.
