(keitai-l) Common web sites on J-Sky Internet

Another question to those in the know:

when I had a CoDoMo phone, I could -to some extent- access any web site 
on the glorious net. For example I could use google.

Trying the same with my new Voodoofone gives me an error along the 
lines of "this peji cannot be accessed with J-Phone".

Am I missing something, or does this really only work with D phones?
