Assuming you are still on Sprint and have no plans to use the SIM Card (GSM Features) or travel overseas than you the standard Radio should suffice. Just make sure to grab the latest PRL. Also, NRG was kind enough to already include Sprint Provisioning for these ROMs, so you should be good to flash (after HardSPL) and enjoy. (These latest builds have just about every kink worked out and soo much faster and more stable than Carrier Releases...)
