Just curious, b/c I don't want to pay a HUGE data overage. I get my home phone voice mail sent to email, which I can access and listen to on my iPhone. Each attachment is about 800 to 900k. So far after 4 days with my iPhone I have received 10.4 MB of data, most of which is from email, only some from a WiFi connection. Just would rather be safe than sorry! Thanks in advance!
