"Hey guys, I work for earthlink wireless, our main product is the 7250, and yes they are set up for EVDO. We (the wireless carriers) just need to flip a switch so to say to turn on the EVDO ability on. The 8700 will be coming out for sale shortly however we do not have a set date! I will keep everyone informed as I find things out! If you have questions please feel free to ask me,"

I have the 7250 with earthlink so I hope it is true!
