I have had several 1020's, 10 in fact that all suffered with the same issue. When talking to someone, it sounded like they had a lisp. this was only previlant when listening through the normal ear piece speaker. It only did it when connected, ringing tone was fine.
Thought it must be the phone so sent it back, then again and again...
Tried hard re-set, soft re-set nokia recovery software, the lot. All phones did it. they were all yellow, sim free. Now, I am currently on a Vodafone 4G contract. Each phone has been sim free. Sim card has been changed more times than I have had hot dinners.
Strangely enough, I updated the audio settings to version 2.1.4.1 and it has got massively worse!!! so much so that it's almost un-useable. And, users at the other end can also hear the lisp and it's terrible. So much so that I am going to hard reset the phone again and not carry out the audio update.
I also noticed that although I had not changed my volume settings, the phone was definately quieter. Shame, this is one update that's a complete screw up. However, it would lead me to think the lisp issue is sofware related and not hardware.... perhaps....
