I plan to switch from a Blackberry to a Droid X but I first want to learn if the Droid X has the operations I want. Q1 -- I currently do not have a gmail account. What additional capability does gmail add? I want to do the following email operations with the Droid x: Q2 -- Can the phone receive email from my existing mailbox on a pop3 server but also be left on the server? Q3 -- From the phone, can I delete selected emails from both the phone and server. Q4 -- From the phone, can I delete email, from the phone only, all emails older than a date that I specify -- without effecting the server?
