Hi all nerds! I am currently VERY unhappy with the Squirt (Sprint) network. I would like to take my Optimus S and flash it to Cricket. Couple questions::::: Would I have to root it 1st? Does flashing it to Cricket offer me full-access to everything like the market and such? Would it be easier for me to root it, then flash it? or what? And, is there a site to do it myself? Please supply the site! I've looked everywhere and I think since its a newer phone, its not available yet.... Does it matter if I burn the ESN or should I get it cleared 1st?
