I updated my Xperia X10 to the latest firmware yesterday, and since then, the mobile version of my website (PDA-template) displays an error message:
"error on line 1 at column 158: xmlParseEntityRef: no name"
my guess is that the phone uses a new Device identifier that is not known to the WURFL database. If so, is there a way to set a "default"-device in case no device entry is found? Or might this be a different problem?
