Hi guys so far i've encounted Week 33 being the 4th and 5th digit with 4.0.1!
anyone know what 4.0.2 will be? i'm planning to buy an iphone 4 but don't want to buy an out of box 4.0.2 so i cant unlock it. tyvm for your help!

Hate to say it's too early to tell, though we should start getting reports in the next few weeks. Buddy of mine who replaced his iPhone 4 at the Genius Bar last week got one with 4.0 on it still -- so they still have stock of devices with 4.0 and 4.0.1, depending.

4.0.2 are coming as Week 34 in Hong Kong

I got stuck with a 4.0.2 4g today at the Aspen Grove Apple Store in Colorado.

Last night, some douchebag stole my recently jb'd/unlocked 3gs. I left it on top of the car and instead of being cool and taking it inside the store, they just took it.

So I got screwed twice over...

Got a 32GB and 16GB both are week 33 and both are on 4.02

yeah man I got all excited because I was able to get two 16gb iPhone 4's from Apple and then I find out they are week 34...meaning they are on 4.0.2

Yep -- it looks like this has been pretty well confirmed, the absolute latest 4.0.1 devices I'm seeing are week 33, and the earliest 4.0.2 devices are week 33 as well. Seems to be fair to assume that week 32 and prior for 2010 are 4.0.1 devices, week 33 would be hit or miss.

I have week 33 and both are 4.0.1

32GB week 34 on 4.0.2, as expected.

Well guys from what i just got i checked the date of the iphone was made it say XXX025XXXXXX in the serial number and thinking it was week 25 .. but i was wrong .. the phone is in 4.0.2
