Getting Email Via Bluetooth And A University Lan Rj45 Connector

[Alan_PAS]

I am in a hectic graduate program and would find it extremely useful if I could access the multiple lan access rj45 plug in access sites throughout my university with my bluetooth pda.
Does anyone know of a wireless/bluetooth adapter that I just have to plug into the rj45 connector of the university lan to permit me to access the internet with my pda via a bluetooth connection?

Thanx ahead of time.
