Many of you might have wondered what names Apple gave its different versions of iOS. Well its your lucky day! Steve Troughton-Smith, a developer, has revealed code names for all iOS versions starting from the baseline i.e iOS 1.0.

Though Apple’s iOS code names don’t get the kind of attention which Andriod code names do, it is still interesting to know what they are, while they might also explain why Apple gave default login password to the iOS which all jailbreakers have come to depend upon.

Here is a complete list of all iOS internal code names.

1.0: Alpine (1.0.0 – 1.0.2: Heavenly)
1.1: Little Bear (1.1.1: Snowbird, 1.1.2: Oktoberfest)
2.0: Big Bear
2.1: Sugarbowl
2.2: Timberline
3.0: Kirkwood
3.1: Northstar
3.2: Wildcat (iPad only)
4.0: Apex
4.1: Baker
4.2: Jasper (4.2.5 – 4.2.10: Phoenix)
4.3: Durango
5.0: Telluride
5.1: Hoodoo

If you are one of those jailbreak maniacs , you might also know that the default password if every iPhone when connecting over SSH is “alpine”, the code name which Apple’s engineers gave to it’s first ever iOS.

Though far behind Google’s desserts, and not indicating anything useful to us, it is still an interesting read!
