I just got an unlocked Javelin and wanted to know if there is a way to set up personal and corporate e-mail push w\o having to sign up with a cew carrier (Javelin is T-Mobile, I have AT&T)?
Blackberry services run thru your carrier's systems, so that certain components will work correctly. You'd have to configure those email accounts through ATT's BIS. Just gotta make sure that your BB isn't already registered in RIM's systems, if it is you might have to contact RIM to have it deregistered.
