You could use the wi-fi via the browser to check the emails online.
Blackberry's have push email, and no other way of connecting to the mailbox. i.e. you cannot natively setup a mailbox that you connect to whenever you want.

Having said that, some carriers are requiring you to have a blackberry data plan even to use wi-fi. As wi-fi is controlled by service books [everything is] which you don't get if you don't have a blackberry data plan.

Blackberry doesn't sound like the device for you, and perhaps a newer nokia with the same fuctionality you have now would be a better choice.
