So the day is finally come! Sunday I get to upgrade my phone to the Droid. I'm looking over all the options so I can just be in and out as quick as possible. Under the PDA/Smartphone Email option there is -Email and Web For Smartphone and -Unlimited Data Usage What's the difference between the two? I'm only looking to access my Google Mail accounts from the phone or via the web on the phone, I'm not doing any Outlook or Exchange syncing.
