If you want to IM me I can walk you through the process with nextel. I had a rep confuse the Hell out of me but I figured it out on my own. It really is not that complicated. What data plan do you have?
Have you tried to go to www.nextel.com/blackberry
You need to set up your email account on your blackberry yourself before you can access the Blackberry Internet Email service for Nextel.
Open up the browser on your BB under the Links you will see Blackberry Email Setup, it will walk you through the email set up for your blackberry email address.
After that you can go to the link above and set up your POP accounts and others.
My IM is
on MSN if you need help.
