What if I don't have WAP browser setup as an option?

Incidentally, the only reason I am interested in this is because Citigroup has a wap feature thru which you can make credit card payments. I have the Browse WEB (aka Blazer) browser, which is supposedly a WAP browser, but it always gives me "page temporarily unavailable" errors when I try to access the site:

(https://w.accountonline.com) only one "w"

What about security? waptunnel says something about it being insecure since it's public but does the "https" still make it encrypted?

TIA
