I’ve just updated the firmware on my iPhone to version 2.0.1 (after much buzz on the web about its speed improvements).  The update applied fine, and my phone does seem a bit more responsive – however it throws an error regarding my carrier settings update failing each time I connect the iPhone to my computer.

See below:

Not sure what the update is or why it failed… however it seems that others are having the same problem.  I’ll be trawling the web – if anyone finds a solution or reason for the problem, post a comment!

Update: This has now appeared on ars technica and on the Apple Support Forums as well.  We are all still waiting for a fix from apple!

Further Update: This problem seems to have resolved itself (please comment if its still effecting you).  I am no longer receiving this error – however this may just be my location – I’m on Telstra 3G in Australia.
