Many of you may have noticed that Google is known for giving codenames to their Android builds, but we have never heard any name or news regarding the Apple’s most popular iOS codenames, well it seems finally we have a little information regarding the internal codenames of the iOS. The newly famoused iOS developer named “Steve Troughton-Smith” has just revealed the all codenames of the iOS from the scrap. i.e iOS 1.0.

However, Apple has no good choice for their internal iOS codenames like Google has the sugary flavor for their Android builds such as “Ice Cream Sandwich.” The iOS internal codenames brings a silent question our mind, which may be answered of iOS jailbreak. It appears Apple has given the default login / password to the iOS through which every jailbreaker access on its device for performing several restricted tasks on the iOS.

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

4.1: Baker
4.2: Jasper (4.2.5 – 4.2.10: Phoenix)

If you are one of the oldest jailbreak users, you might have knowledge that the default password of every iOS device is “alpine”, which seems to be the internal codename of the first iOS by Apple, which was released in 2007 with first gen iPhone.
