Why are there two jailbreaking tools for 4.1?

[LoneWolf121188]

Just wondering what the difference between limera1n and greenposi0n are from a technical perspective. Do they use the same exploit? If not, why release two tools that do the same thing two different ways and let Apple patch both exploits?

Same exploits for both.
Some like coke, others pepsi

There are 3. You left out redsn0w. Soon there will be 4 when PwnageTool comes out.

Maybe we need a fifth?

The answer is that both Geohot (author of Limera1n) and the Chronic Dev Team (authors of Greenpois0n) have been working on tools using different exploits for some time. When Chronic Dev was almost ready to release its tool, Geohot contacted them and asked them to delay their release so that they could rewrite their tool to use his exploit, which he claimed was already known to Apple. When they said that they would not, he vowed to release his before theirs so that they would do "the right thing" and save their exploit for future uses.

Since Chronic Dev had put so much effort into making their tool, they were reluctant to delay its release. While they were discussing what to do, Geohot released a very rough beta of his Limera1n tool to force their hand. Since they did not want to waste an exploit but still wanted their hundreds of hours of hard work to see the light of day, they decided to rewrite their tool to use Geohot's exploit and released it as Greenpois0n, saving their SHAtter exploit for future use.

I read somewhere not sure if it was true or not that the Shatter exploit was only going to work on Iphone 4's.

For me still being a 3GS user limerain was a godsend

Same reason you find multiple "tool" at home depot.

They are using the same Exploit, they are just coded and implemented differently by 2 (actually 3 but the 3er hasn't been release yet, will be here soon) groups.
