Give it a try.... It may or may not work.
(Make sure you have BlackBerryOS 4) ...
You will need to use a third party web browser such as Reqwireless from www.reqwireless.com
.... And it's possible software such as www.verichat.com
would work too (try the "non-BES" version)
Please report back to me if any of these works for you.
