hahahah 1.1 ah i remember when jailbreaking was as easy as AppSnapp...
anyway, if you wanna stay on the original, download quickpwn, google it
and if you want to get a 3G, also, quickpwn, it doesnt require a restore. thats always good
there is also "pwnage tool" that jailbreaks the firmware, then you restore the phone with itunes.
and youd get a jailbroken phone.
so download the 2.2 firmware, once again, just google it.
sorry about not posting links to everything, im kinda in a hurry :/
