you can manage your profile/emails for pre here

EEK I can't post url's but there is a palm portal for managing your pre profile, once I post 10 things I guess I can post..

also a big tip for folks having trouble with roaming, I did.

go to phone / preferences

scroll down to preferred roaming list

and do an update PRL

once that is done

go back and do an Update network settings.

if you travel to a new location, turn off phone, repeat this process helps get proper tower coverage.
