W880i: "The request is not understood"

[#1]

Build-in browser starts to give an error 400 (bad request), though url is right. It doesn't open any page at all. Not sonyericsson.com, not even google.com. Opera Mini works fine, but in attempt to download application, or update it, Opera redirects me to build-in browser and the same 400 error happens.

I can't connect to update center either, connection fails.

I didn't change any settings. Month ago or so all worked just fine. What happened now?

Try phone repair via PC suite and/or a master reset.

Thank you!

Problem solved: my operator recently changed settings for GPRS and MMS. I received message with new settings yesterday. All works fine now.
