I have a first generation ipad running ios 4.2.1. I wanted to download an app that requires at least ios 4.3. I see that the ios currently available is ios 5, but I have read there are problems with that ios on first gen ipads. I do NOT want to upgrade to ios 5. I tried googling how I might update to just ios 4.3 but understand you have to have saved SHSH blobs for the version you want to install, and whole lot of other stuff that sounds like jailbreaking. I am not interested in doing that. Here is my question, (finally) since my iphone 4 is currently running ios 4.3 is there a way for me to upgrade to that ios in itunes somehow? Any help would be greatly appreciated. Thanks.
