Echo in iphone call - hardware or software?

[kaslar]

Hi Everybody
I've bought a USA 1.G 16 Gb iPhone and besides ONE thing it works perfect.

I've tried 1.1.4, 2.0.0, 2.01, 2.0.2 firmware and the same problem is everywere:

The person on the other end recieves a echo of themselves when making a call. Apparently the speaker( when turned up to the max) goes down into the mic and therefore creates an echo. Turned down It's not a big problem, but I'd like to used the full volume everywere.
Lots of people have tolded me that it's too annoying, and ussually the conversation ends really quick.
Now I've tried to sell the phone but nobody wants a iphone that doesn't work perfectly.

What do I do? Is there anybody out there with an advice? Can I fix this myself?

I live in Denmark, Copenhagen and I've tried with a lots of other simcards and networks (3 simcards on 2 different networks)

I am experiencing the same problem. I have no advice for you. I guess I am going to upgrade to new phone. I have searched the internet for solutions. I haven't found anything that works. Let me know if you get any results.
