Most of my emails that I recieve have many people copies on them. Is there a way to reply to all. I have an at&t blackberry 7250 I think.

As long as your e-mails are being pushed/forwarded properly, just hit "reply-to-all" off the thumbwheel, and it will do that.
If you're recieving e-mails on your blackberry that should have a number of addresses on it, but only show your address, you will have to modify how your e-mail is being sent to your blackberry: server-side-rule/re-director, etc.
