Jailbreak iPhone 3G v.2.2.1 possible?

Hi,

How you guys doing, I'm sorry if this has been asked before, I am new to this community, and I have never Jail broken my iPhone, not really sure how I can do it either :(, but I do know the version I currently have on my phone matters, so is it possible to jailbreak phone with v 2.2.1? I am on AT&T carrier (no need to unlock)

Any help on this matter would be greatly appreciated, I have done a search with no luck yet..
Please excuse the ignorance
Thank you very much in advance, for your time and help on this
:)
