Reactivate Phone after Flash and Updated Rom

[chaptap566]

Hello PPCGeeks!, This is my First forum post, even though i have been around the website for a week or so now, reading and learning. I am A total Newb, however i have figured most of it out for myself. I finally took the big plunge today, and was able to Flash My verizon xv6800 to cricket, and get the sms and wap, and gps featured on the phone. I used Oilpro 2.4 to unlock my phone. Then i used PPC Kitchen and updated everything, and reloaded my rom onto the phone. Everything seems to be working fine, except how do i get my phone working again? as i said i have been looking around, and i see something about carrier cabs or prls, i think these have something to do with it,..im not sure what these are and how to go about fixing it. If someone could point me in the right direction i would be most appreciative. Thx for your time!
