I was thinking of making this upgrade myself. Any success? Edit: Or maybe not... http://www.cnet.com/5420-7874_1-0.html?forumID=105&messageID=1760626&threadID=157895 My ancient Dish 4900 hasn't been plugged into a phone line for eons and it has latest software update. I also don't get charged $4.99 for not having it plugged-in. Is this guy BS'ing me?
