Nokia 6255i / 6256i

I'm having problems finding/viewing web pages on my Nokia 6255 (Alltel). Whenever I search for a page on Google (using Mobile Web search or regular searching), I get this message: "The requested page cannot be displayed." I'm not doing complicated searches. Even something as basic as "sports" gives me the same non-response. The only web pages I've been able to view on my 6255 are ones that I've guessed the url for or found the wap url using the web on my PC (ESPN, ABCNews, and Yahoo are the only three I can get!) There must be an easier way. Anybody know what it is? (BTW, I called Alltel tech support and they were no help.)
