I was looking at their site a moment ago, and on Virgin Mobile's "Question and Answer" page for the Samsung Intercept, someone posted an answer there saying that there will be an update by the end of January. I am not too sure how reliable that answer is.
I am pretty much like everyone on here: on the fence about rooting it. Right now, I am holding out for an over-the-air update from Virgin Mobile. I guess we will have to wait and see how that goes. The phone that I have is pretty sluggish and I have a few problems with it here and there. I have read somewhere that the Android 2.2 is supposed to be 2-5 faster than 2.1.
