I was charging my phone and when I touched it to pull it from the charger there was a large visible static spark. The screen went grey but the notification led was blinking green. I pulled the battery and cycled the power and I could here the sprint startup sound and then some notification sounds. My phone is rooted and now there is no way to unroot before I take it back to sprint. This is my second evo, part of the touchscreen went out back in November. In November I paid a $35 fee and sprint had a new (referb) delivered the next day which is what I plan on arranging tomorrow. When this phone is shipped back to HTC will they know or care that it was rooted?
