4.3.5 to 4.3.3??

[woko0291]

I've been coasting through alot of these threads and have not been able to get a straight up, non-vague (is that a word? w.e) answer, so just thought i might create my own thread.

anyways i bought an unlocked iphone 4 with a gevey sim a weeks ago running 4.3.5 and ive seen posts about all the firmwares not requiring some type of security clearance? and that you should downgrade 5.0 while you still can without a problem. Since i have no interest in running 5.0 just yet. Ive also seen dozens of post stating that i need shsh blobs or w.e and im a bit confused. is there a definitive way i can downgrade to 4.3.3 so i can just manage with that tethered jailbreak?

i dont want to upgrade cause im using a gevey sim and don't want to cause unnecessary problems for myself lol. Not to mention ive downloaded every possible jailbreaking/downgrading tool that might help

help?
