    Yes it can. use greenpois0n

    go to GreenPois0n

    It's an untethered jailbreak by the way.

    Do a search on the forums to see the problems people have run into while trying to JB with Greenpois0n just incase you encounter the same problem. It is simple and quite fast, make sure you backup and sync your phone before you do the process. Once the process is complete make sure the first trip to Cydia you backup your SHSH blobs by clicking "Make my life easier" and you should be all set to rock and roll.

    Greenpois0n is not tethered, it will either work or not work for your model I think you have an MC model. I remember there used to be an issue, don't quote me but I don't think it matters for 4.2.
