Without the switch, there were suddenly only two choices: whether or not a data connection. The switch was iOS 2.0 was first introduced.
The 3G switch is on the iPhone 4S absent on older models, the switch with IOS 5.0.1 can still be found.
In iOS 5.1 beta 3 is also a reference to a new feature for iPhone users spotted: dictation of texts. A legal warning 'About Privacy and Dictation "indicates new dictation on the iPad, though they are not actually found in the new beta. The warning is different from a similar warning on the iPhone 4S. It seems that Apple's iPhone in the future will offer Siri-dictation, perhaps in a new model or via a firmware update. It is also said that warning of Siri-dictation in the latest generation iPod touch is detected, but this is still unconfirmed. Improvements in battery life are not reported
