Hello! All

Im new to this whole cell phone phreaking suff and I was hoping that some of you would not mind to take the time to educate me.

Im not sure if this is too farfetched but I would like help with this:

1. Can I use a cell phone to make calls without charge to me?

2. Is there some type of equipment that I need to flash these phones so that i can get it to work in the manner listed in item 1?

3. What cell phone would be ideal?

Thanks in advance.
