first off: thanks e-yes and everyone that contributed to making Nitdroid work for the N900 i installed 2.3.1 without a hitch in early april, and because of that i didnt upgrade to Vostok when it got released. now if i want to install UMay, do i need to uninstall 2.3.1 then install UMay as per the wiki? or can i just use the steps for "Upgrading N11 to N12" in the wiki instead? i looked through all 12 pages of this thread and didnt find the answer.. i hope i didnt miss that post. thanks in advance
