First, I think you can remove the following topic about this bug, it's mine... (Sorry I thought my request didn't work... ^^ )

So then, I will give you every info I've gathered:
- The 2.1 upgrade is an official one. Update avalable in paris/France
- This problem only concerns 1/4 or 1/5 of the channels. (Don't worry, many others still work... But not really the one I listen to). BUT I've been unable to find a similarity between the not working ones. I've tested different (about 50) bitrates, formats (mpeg/AAC) , genres, I didn't really find a clue...
- This problem only happens when receiving data with 3G/HSDPA. With WIFI everything works fine.
- Last thing I can say is that everything was working fine before this update...

If needed I can also give you a few examples of non working channels... Tell me if this can help...

Thanks for your time... (and sorry if my english is not perfect ^^ )
