It is still unclear who has made it possible to jailbreak iPhone 4 CDMA as the team behind this stuff has no other name apart from the ‘UnthreadedJB’. It is rumored that this jailbreak uses the exploits released much earlier by the members of jailbreak community, however, whether this is true or not we don’t know.
There’s also one drawback about this jailbreak -- it is currently working on Linux only. But with time it is sure to reach other operating systems.
