Default [Q] just curious

I just got my e4gt and I love it...only issue is it's not active on any service(though it is a sprint phone) I've seen a couple threads on how to flash it to VM using a couple different phones. the phone I have though is a Kyocera rise(it's ok...) i'd really like to use my e4gt seeing as I already have it rooted and running a custom rom but i'm not entirely confortable with flashing as I've never done it before. any tips for a n00b flasher?
