Don't act like Verizon didn't warn you: for Thunderbolt owners who see an available software update pop up on their phone this evening, they'll be placed squarely between a rock and a towering boulder. Why? On one hand, the Froyo OTA update promises to nix random reboots, improve data connectivity and fix the Bluetooth Discovery Mode pop-up windows. On the other, it adds a helping of bloatware (V CAST Music, V CAST Videos and My Verizon) while also killing the lust-worthy free mobile hotspot feature.
