As long as you have a l710 with virgin mobile you won't need to edit anything for this, eb has already done and it
As for you question, no, the asserts in the phone are basically a line that says this is a sprint, VM or whatever phone, the reason editing is required at all is because most Roms built for this device are built for the sprint version which is identical to ours, so we edit the sprint lines out and make the VM lines, or remove them altogether
But in this particular forum there are already at least I believe 2-3 Roms which don't require you to edit anything
