thanks for your answer.
I'm sorry but the 7230 was already sold on ebay as defective (phone works but no USB-Connection)
Oh yes, it hits the street to much only 5 days after I bought it. Very bad.
With the 7230 I was not able to place a call near a high traffic street (I hope you know what I want to say)
I can't understand the other person very well - which was NOT caused by language differences
Some people here in Germany said the quality was much improved on the 7290.
Thanks for any comments etc.
Have a nice weekend
