do it to be on the safe side, it doesnt hurt u one bit. Trust with the stock rom u will prob have to hard reset a few times hehehe.. upgrade to phoenix 3.5 before u go to 6 since there is so much on 6 that might overwhelm a newb LOL jk enjoy the phone btw..

I say upgrade to whatever u want because thats the only way you will learn, just keep a backup phone incase u get too crazy and brick the phone.

as far as chargers go, i use the same one i charge my BT headsed sometimes the camera cord when i am at work, or through the usb hub on my car stereo. cheap or oem works the same to me.. the cradle that came with mines is still in the box somewhere in the garage, i never use it
