So I understand that Verizon will offer the Droid X at the Upgrade price to anyone with a Upgrade in 2010. Mine is in November. I wold like to go from Droid to Droid X. However, I would only do it if my Droid was worth enough on eBay to cover the costs. So far it is with 50 bucks pocketed. My question is, will my ESN be clean if I take the early upgrade option? Or will Verizon lock out my ESN, preventing me from selling the Droid at full price? I know normally after an upgrade they don't do that, but since this is a special upgrade, I thought they might block them. Thanks.
