I would suggest 4.2.1
Download sn0wbreeze 2.2
Cook a custom firmware with baseband preserved.
Put phone in pwned dfu state
Download ultrasn0w .

Yes. you can use PwnageTool for Mac.
Select Expert mode, phone, firmware, check activation if you don't have an official SIM and follow the remaining steps all the way to the end (including the pwned-DFU countdown timer). Then continue w/iTunes (shift/click/select cfw). Done.
BTW: The latest version you could load is 4.3.3 .. but most agree 4.2.1 is the best overall iOS to load.
