Iphone 3gs activation problem after updating ios 5
If you’ve recently downloaded an i OS IPSW file, you might be curious how to use it to update your i Phone, i Pod touch, or i Pad.
Using IPSW is often considered advanced but it’s actually pretty easy, just follow along with these directions and you’ll be along your way.
Not all versions of i OS IPSW will work on all devices, so be sure to select the proper version for your hardware, and to use the latest which is supported.
Typically a normal i Tunes based restore is sufficient, which is why that is fairly rare.
If you go that route, do not forget to backup beforehand.
Though the average user is better off going the easy routes of updating i OS with i Tunes or OTA, IPSW can have very practical uses as well.
Hactivation is the process of activating your i Phone without using an official i Phone carrier SIM.
Until now, you needed jailbreaking tools like Pwnage Tool to hactivate your i Phone.
