Ive been thinking about making a custom rom for Cricket. Yes, I know there is already one. I would make a stock rom, with a custom kernal with overclock and iptable support. Add a few apps like Root Explorer, ConnectBot, SetCPU, Autostart, etc. Then save it as a nandroid backup. All you would need to do is flash recovery sbf, restore nandroid, manually program, and edit the EVDO tab in CDMA WS. Would be like a 20 min flash.
