I would just flash the radio from 4.0.3 (UVLE1) instead of the whole 4.0.3. 4.0.4 is pretty universally considered a much better version. The UVLE1 radio seemed to fix my issues, and that way you still get to have 4.0.4.
I believe you can flash the radio even if you decide not to root... although that's not the way I did it. I rooted mine so that I could have the peace of mind of having a Nandroid and Titanium backup.
