problems with this app ipod touch 2nd gen

when i first got this app it worked great up until about 3 weeks ago when recording a track after about 30 seconds i get a lot of mic feed back then the music stops or during playback of old recordings mic becomes active and track stops i just got the update for the new 4.0 software and the same thing anyone with the same problems or suggestions

i got the same problem as you and iv been reporting it to Smule many times and they dont write anything back to me. I wish they would fix it because its my favoret App.

turn off Wi Fi when recording to make mic feed back go away.

still having problem with this app when playing a recorded track mic becomes active and song stops,I have gotten a few emails from smule but still no fix I tried reinstalling the app and turned off the wi fi and still the same problem
