I got an used BB 8310 from the company where I'm working a few weeks ago.
I disabled the it - policy first and tried to connect my Black Berry with my Yahoo Mail account, but this doesn't work. I can only connect to Business Enterprise Servers, says my BB.
How can I get a connection to my Yahoo (pop3) mails ?

By BlackBerry Data plan, it's do you have a data plan or a voice only plan on your phone?
If you went from a regular, non "Smartphone" to the BB and didn't update your cell phone plan, then you might not be able to because there's no Data Plan associated with your account, meaning any data (e-mail, web browsing, IM) could be blocked.
For sure no matter what you want a data plan as part of owning a blackberry. There's a good posibility if you don't have one you'll pay something ridiculous like $100 for 10MB of data.
