Hi Rob, Yes, it is. I tried using SDK 3.2 on an iPhone 2G running iOS 3.1.2 and SDK 4 on an iPhone 3GS running iOS 4.0.2 and the echo suppressor seemed to work fine. So honestly, I don't know what may have caused the echo suppressor not working on your side, but my guess is it may be due to the SDK and iOS compatibility issue (there was a report that echo cancellation doesn't work using SDK 4 on an iPad running iOS 3.x but works fine using SDK 3.x).
