Hi, I'm Gar, I'm a non techie guy that owns an I pad. I'm not sure where to post this query that I have in mind. And will appreciate if anyone can direct me to the proper forum or answer the question directly. I have an iPad 1st gen running on iOS 4.2.1. I missed th updates from apple to upgrade the os to 4.3.3 and I want to upgrade my iPad to that particular version. (my iPad is not jail broken). Can I download the 4.3.3 Ipsw and restore using the downloaded file via iTunes?
