Spidered by Inktomi Slurp but not in Yahoo SERPS
 

What am I doing wrong? Or, what is Inktomi Slurp spider doing wrong? My website is deepcrawled by Inktomi Slurp about 2 times a month, everyday the spider crawls 15 of my pages but when I go to Yahoo! and search for "Sprint Total" my old URL appears, but the "new fresh and deep crawled for about 1 year" address doesn't appear in SERPS...

What is wrong here? Is it me or the spider? My website appears on Google, but i'm having problems with Teoma, Altavista and Yahoo!. I'm also using a 301 redirect from the old to the new URL.
