That shouldn't even be a question lol. Keep your X and wait. Here's why I say that. The iPhone 4 will be outdated by the time spring gets here. I'm sure they are coming out with a 5. Then you have the HTC Thunderbolt coming at the end of this month(I have a real reliable source). Also the bionic coming in the spring. Its to many good devices coming to just settle for that phone IMO. Im with sprint, but they are letting me go. I have an evo and I love it. I'm coming to Verizon because its the only other carrier that works where I live. That's how I got the scoop on the thunderbolt. I know waiting sucks, but you will be happier if you can hold out for just awhile longer. I did for the evo, and I'm glad I did.
