Ok I have Three questions

1 If you use the POP3 account and delete a email does it delete it from the server? I have try this and each time I deleted it the email comes back the next sync.

2. I have yahoo mail service. Went using the POP3 account I would have yahoo sent me a text message to cause chatter to sync which was great. But sense I could not get the delete to work on the POP3 account I have forward my email to fastmail now the text message won't work. Does anyone know of a IAMP service that would send you a text message ? I don't want to drain my battery too low and I need to know when a email comes in.

3 Does anyone know of a way to get a invitation code from gmail I have try with both my phones and my wife but could not get the text message sent to me.
