Yes we have the sprint version of the s3 yes it should be able to run sprint roms without a problem does it no the problem is we have the same phone different software while our software is called md7 I believe same as virgins sprints is md4 and both virgin and our gs3 are on the ics bootloader which makes cm unable to install because it wasn't built for the ics bootloader only jb bootloader and that's why we need to flash sprint's firmware to get the jb bootloader then flash cm 10.1 and it's going to be a time consuming process but if your ready
You'll need this http://db.tt/PJKerheQ it's our modem bin
The rest is pretty much self explanatory you download the sprint md4 firmware then delete the non-hlos.bin and replace it with the one above then download cm 10.1 put on your sdcard along with the sprint md4 firmware then
Flash the firmware let it boot connect to the boost mobile network you'll know if it's working by going under settings and about phone and status you'll see under network boost mobile and mobile network state should be connected if you have mobile data turned on (3g/4g) then go back to your recovery and flash cm 10.1 and you should be good now.
For the 4g I believe you need the apn and need to change it to boost Apn so here's the apn http://db.tt/jCXZ1hGX you download the app apn backup and restore it's the first app if you just type apn in the play store and use the app to restore the apn read the description of the app please it'll tell you you need to make it a system app using titanium backup and as far as restoring the apn to get 4g once you download it the apn will be in the downloads folder you need to use your file browser and copy and paste the apn you download to the location of apps folder I think the folder is called apnbackup or something like that if not back up your current apn then go find the folder and paste it there and restore and you'll have 4g hopefully I haven't had time to test the 4g so Idk if it's going to work but it works for a guy on virgin so we should be good
Don't blame me if you brick your phone I'm sorry I can't control that but be warned on twrp I'm having issues with this for example once I flash cm 10.1 and tried to go back to stock via a backup it wouldn't let me then I tried a factory reset it failed because I believe my permission got changed somehow moving from stock ics bootloader to the jb bootloader, I tried to fix permission and it failed also saying I had to let the rom boot then fix permissions... It's aso the long story just know once your on cm 10.1 getting back to stock is a pain, it may just be me but I'll let you know if I can fix find a fix or way around it .... And um just beware you might mess up your phone if you do I'll try my best to help but I can only do so much thanks and any brave soul can give it a shot let me know what happened
Alright on twrp there's an issue with installing cm 10.1 and going back to stock and reflashing so you have to do an extra step to get it to boot or it won't after you flash the md4 firmware you have to hit reboot recovery and I'll freeze so just pull the battery and power it back on and I'll boot
