Just a thought. It came to me the other day. But I noticed Tmo has an HTC phone with ICS (Sensation) as does At&t HTC Vivid with ICS then Verizon has the GNex already. So with that being said maybe its one big conspiracy to get one maybe 2 phones on each carrier running ICS. As far as Sprint I'm not sure if they have one or not yet. I just find it odd or maybe I'm just too paranoid that our Rezound's wont get it anytime soon. Which I'm still praying it just comes any min. But there is another thread I seen that made alot of sense about the Fireball and One series coming out before we actually get the official ICS build OTA.
PS. I rooted my Bolts and really dont wanna root my Zound.
