Ok Im thinking about finally pulling the trigger on getting a Thunderbolt. I dont know much about Rooting. I have heard though that you can get the phone to go faster, remove bloatware, free tethering, and a few others. Well the biggest thing I want to do it for is the free tethering. Is rooting your phone really all that better? I have hear that it will void your warranty. Will they void your insurance too or no? Can you unroot the phone if I was to send it back for warranty or insurance purposes? Well hope to hear from you guys soon. Im looking forward to getting the Thunderbolt hopefully soon.
