So I am considering rooting my MT3G. It came with 1.6 stock. I understand I have to revert to cupcake in order to root. My computer does not have an sd card slot. Am I SOL here, or is there a way to revert to cupcake without having to remove the sd card from my phone (which is my only way of accessing my sd card on my computer)? I could go use my sister's computer, I know her's has SD slots, but I want to see if there is any other way before I drive to her house across town. Any ideas are awesome.
