no jailbreak required :) – thank verizon (& fcc) for shipping factory unlocked iPhone 5! yes it works on h20, straight talk, etc

you just need to cut the current gsm sim card, put it in and vu a la – it will work! (i’ve got it working with h2o and t-mobile) – no jailbreaking / gevey required.
here are the instructions:
1) cut the sim card to nano size.
basically take the current nano-sim out, put it next to your current sim card and use a big knife :)
here’s a very helpful printout
tip: use an old, non wokring sim-card to practice
2) in order to change your apn settings so Internet works, you’ll need to enable “cellular network data” option under settings > general > cellular.
t-mobile sim card ($20 at any t-mobile store) is your ticket
then, use this sim swipe trick:
then change your APN settings (e.g. h2o, here are others)
(when using gsm, 5 supports up to 6gb down speeds – “4g”)
ps: good luck and check the news before you upgrade iOS 6 (when update comes out)
