I am leaving my Nokia phone and have been researching what new phone to go to. I have rejected the iPhone and settled on the Hero based on multi-tasking and the ability to change the battery. Here's my question about the Hero, which could be a deal breaker. My Nokia has a setting whereby my telephone number is not shown on the called party's caller-id. In other words, when I call someone, their caller-id says "unavailable" "blocked" or something like that and does not display my telephone number. Does the Hero have the ability to block its caller-id?
