The following is taken from Apple iPhone School
GeoHot, the developer of the purplera1n jailbreak, has just added an entry to his blog and this is what it says;
“And prepare to meet the program that will jailbreak them all. ”
Yep, you got it, he apparently has found a jailbreak that will work with all iPhones and all iPod touches on the 3.1 firmware.
He also says, “no affiliation to greenpois0n. and it’s in some ways the complete opposite of purplera1n. but still 10 seconds. and may work for every version of software *ever*, based on the prettiness of the exploit”
We will keep our eye out for more info.
