Is there anyway of finding out the manufacture date or what ios is most likely installed via the IMEI number of an iPhone?

Looking at buying an un-opened iPhone 4 here in Japan for a friend but I need to be sure I can un-lock it as he'll as I'm sending it back to New Zealand. The guy selling it *thinks* it'll most probably still be ios 4.x.x but I'd like to be sure before buying it.
 
Thanks for the info! I might just get him a 3GS to be safe. They're un-lockable on any baseband right? ios 4 - ios 5

not an old bootrom on ios5, why not boot the i4, if it has the icloud setup things its ios5, if its a connect to itunes icon its ios4

The guy selling it doesn't want to open the box. They are still sealed in plastic.
 
Look at the serial number (not IMEI). The 3rd digit will be the year of manufacture. The 4th and 5th digit will be the week of manufacture. So a serial number of xx138xxxxxx would mean it was made in the 38th week of 2011

Compare this to the date iOS 5 was announced for release.

Perfect! That's what I was after! Cheers
