Heh, I'm still loving my 2 SERO lines! Somehow I even managed to get a corporate discount on my plan. My company does a 20% discount. I figured, hell I may as well try.. so I submitted for it. I ended up getting it. So essentially, the discount covers the cost of my insurance plan on both lines.
I have even attached a screen grab proving it:
If it ever becomes available for me to add a newer android phone for a few bucks extra a month, I would jump all over that. But for now, even the EVO isnt cool enough for me to drop such a cheap plan.
