This bug affects AT LEAST these ROMs: SL-5500 ROM 3.10, SL-5600 ROM 1.04, 1.10

When a PPP dialup connection is active, "Email" app does not recognize the connection. Note that the Zaurus Dialup Manager software provides a PPP connection. If you wish to use Email and Zaurus Dialup Manager you will need to use a ROM other than those listed above. Note that Opera uses the PPP connection properly on these ROMs.
