I just got my treo 600 and finally gave up the 3 year old Mot phone. The Treo added the ability for MMS emails. But, without me even giving out or knowing the email address, I started receiving about three to five spam and/or virus messages a day. Made me mad so I called Verizon and they had no explanation, so I told them to cut off the MMS on my phone, I can send emails from yahoo in blazer just fine if I needed to do such. I hate spam and junk mail and just thought I would share with others who might feel the same.
