Hey guys, the mods cleaned the thread up a lot, there was a bunch of useless posts and what not. Anyway... 27scoob, to answer your question a few posts back, read my original post about the pros and cons (pg 4 i think) and it was quoted again recently.
I have had personal experience. The BIGGEST issue I had was that when I couldn't figure out why I could not boot into recovery... that was just it, no one could figure it out. I did everything right that unrevoked indicated I do. I downloaded the program for mac, rooted my phone, performed back ups, downloaded ROM manager and install clockworkmod on my phone, and the whole 9 yards. What happened...? I would boot my phone into recovery, and for about 15 minutes, no lie, it stayed on the white htc evo 4g screen. I timed it, then pulled the battery. Not once did I boot into recovery while rooted with unrevoked. It was stressful, and a nightmare not knowing what I had installed onto my phone.
The whole root process is supposed to involve flashing this, downloading that, inserting this here, rebooting, restarting, wiping, etc. Not plugging in the phone, pressing a root button and viola.
I am very happy your root has been successful and continues to be. I hope the best for you and that you get to experience 4G as well, I was lucky enough to twice, in Nashville and DC.
In addition to this, unrevoked forever claims to never lose root. They encourage users to do this, but what about when you have a mechanical failure on the phone (speaker clicking, kickstand flimsy, lose this, failed that... they wont do anything for you with a rooted phone. If you can never go back to stock, you can never undo what you've done. Its rooter beware.
Again, sharing my knowledge, experience, opinion, and chainsaw humor.
