My BlackBerry Tour swam...so I had to claim it on insurance. While waiting for replacement, Verizon store gave me a BlackBerry Worldphone loaner. I've tried validating all email addresses (all validate), then "registering" the phone (options/advanced/host//register), and all looks fine, but my phone will neither send nor receive email. Is there some part of the registration I'm missing? Am I supposed to change the phone serial number somewhere? I need the email accounts for work mail. Thanks!
