I have not rooted my phone because I don't know how and have not had the time to mess with it.
I'm on Sprint, so there does not seem to be a lot of Sprint BS in it.
Sure I could figure out how to root the phone, I can usually figure most things like this out pretty easy.
Since I threatened to replace it, my EVO 4 has been behaving nicely.
Only issue being the battery life, which the single digit temps have not helped.
That and I think I need a new battery.
Not interested in an iPhone. I like my iPod and it works well but I also know a few people who have had a lot of trouble with the iPhone and iTunes.
