Verizon iPhone 5s is Carrier Unlocked Link
From iDownloadblog:
After a few minutes of manicuring the SIM card down to a nano size, I was ready to rock and roll. I popped out my Verizon SIM, inserted my T-Mobile SIM, and sure enough, I was on T-Mobile’s “4G” network.
I wish this wasn’t news. Carrier locking is a one sided equation. SIM cards are how they’ll resist an FCC mandate.
