Hope this question makes sense. I have a verizon HTC One M7 phone, and considering purchase of an M8 to use on GSM carrier (most likely Cricket). When I look at used phone prices, the unlocked / carrier model M8's are less expensive then the google edition versions. Assuming I can convert an AT&T version to a google play edition, is there any advantage to paying the premium for the GPE? My only experience with rooting / installing ROM was to take a droid razr maxx and root it and install Cyanogenmod, but I was ok with it. Would appreciate insights. Thanks!
