+1 to doogald's answer re. needing this... You don't need this until you need it--but it doesn't hurt to have it in-place if you want to. Also, having a wonky trackball later on will not prevent you from being able to install this tweaked-recovery. Also, now that jcase has re-appeared over at XDA, there's still a possibility of creating a 1-click app that will install this alternate recovery just like his 1-click rooting app (I know how to create this app and actually have his source code, but I will not do this or use his source without his permission). doogald, are you thinking of the issues that some folks having booting into recovery due to the different bootloader versions? I.e., http://androidforums.com/eris-all-things-root/205697-notes-recovery-booting-1-5-vs-2-1-otas.html This is the only thing that rings a bell to me... Cheers!
