I live in a rural area and my only option for internet is via satellite. I currently use Tracfone for cell service as we do not use it much. I am looking into switching landline and cell service to VZW and was wondering if replacing the satellite internet was an option if I were to use something like pdanet on the Droid Eris. My questions are: Is the VZW data plan truly unlimited? Will pdanet allow me to use the Eris as my data connection without paying VZW for tefther? Does the Eris have built-in Wifi or will I need a router? Thanks for the info.
