I'm on Virgin, & the only way to get an upgraded OS is to buy a newer phone. I understand that, since they don't hold customers to yearly contracts, they need a different way to maximize profit, but that not exactly a way to endear one to the customers. I've been mulling over hacking my Triumph because, with the release of Jelly Bean, I'm 3 upgrades behind now. Plus there are glitches in my current OS that will NEVER be fixed, so it starts to look better all the time. I just wish rooting was not such an increased risk in security.
