Root [Sprint] Unlocking Sprint GS4

[luis32744]

Hi does anybody know if there is a way to unlock the sprint GS4 to be used domestically within the US with other gsm prepaid carriers. I know there is a way to unlock it to be used when you travel outside of the USA(Which I have already done from galaxys4root.com) but that doesn't help me since I don't travel out the USA. If anyone has some more info please let me know thanks

Got my Sprint S4 unlocked and rooted on 4.4.2 I was actually on the NAE/MDC baseband version and was having issues. WiFi wouldn't cut on and Dailer,lock screen was lagging, Screen would lag as well. But then I flashed it to Cyanogenmod. Works like New.
