Updating my itouch
This is highly recommended to use the time zone and automatic time keeping operation enabled, particularly if you ever travel out of your time zone, as it will determine the new time and date automatically when the location changes.
Next you can be sure that the proper date and time are always accurate on the i Phone and i Pad by making sure the time zone adjusts with your location.
Additionally, it is recommended to use the Time Zone location service to be sure the device updates itself automatically with i OS location detection, correcting the time as needed whenever it strays.
If your i Phone, i Pad, or i Pod touch keeps resetting the time and you continuously show the wrong date or time on the device, it is likely because the battery on the device is being run down, and then it is left off for an extended amount of time.
Sometimes if the date and clock is off on the i Phone, i Pad, or i Pod touch, you may run into all sorts of weird errors, like the inability to send messages, can’t make calls or send emails, some apps don’t open, and other odd behavior.
Having the proper date and clock set on an i Phone, i Pad, or i Pod touch is important, so be sure you have it set correctly and have it set to automatically adjust.
Make sure the i Phone, i Pad, or i Pod touch is connected to the internet in some form, whether it’s wi-fi or a cellular connection.DFU or Device Firmware Upgrade mode allows all devices to be restored from any state.It is essentially a mode where the Boot ROM can accept i BSS.For more information about the protocol, see DFU 0x1222.This is the device ID in the i Pod touch (2nd generation), the i Phone 3GS, the i Phone 4, subsequent 32 bit devices, all 64 bit devices, and WTF mode.
