More data has been revealed about the latest iPhone firmware and SDK build. The latest build is called 5a274D. The new firmware was released on Tuesday, no warning was given, and it has taken a while for details to pour in. We finally have them though, and it seems there has been some significant changes to the build.

The latest build of the SDK is much smaller than previous builds. It weighs in at only 1.08GB. It has been suggested the reason is that lots of redundant cipher was removed. There has been some changes to the API as well. Namely the address book

API, and the Embedded Apple Graphic Library. These changes propose that applications will need to be re written to take advantage of the new libraries.

There is some evidence that suggests that push e mail will be in the 2.0 firmware. The latest build, revealed a toggle on/off option for a setting named “Use Push Mail”. You can plus still opt to have your iPhone fetch your mail at a predefined interval. It is not known all the services that will be able to be pushed, one though is Yahoo! Mail.
