150Mb speed availability

Hello all, Is 150Mb "Ultimate" speed available in the 92630 area code?? I have called customer service and sales, but they both claimed that Cox doesnt offer speeds that high anywhere??? I have seen literature from a co-worker who just got service last week, and in the info it talks about 150Mb service being the new "ultimate" and what was ultimate before is now called "superior". So whats the story?? Is it available here or not??
