Hey guys. I tried android on my phone when it first came out, running it off the sd card after windows started up with haret.exe. I see a sticky for nand booting now. It seems like id basically be flashing an android rom. Is this true? No more windows? And if this is true, will android be running a lot faster than running it off the sd card? Is it worth it? Sorry for all the questions. Ive been reading thorugh the forum but havent really found a direct answer to my questions. I really want to use android for a while before I switch from windows mobile. I want to make sure i know the ins and outs of it, like i know windows mobile. I want a new phone, but i don't want the arrive since it comes with windows 7, but i need a keyboard, so I'm thinking of the epic.
