Thanks
TP - wife's Mini is fine also, but took a LONG time over the cabled connection - believe that I've done OTA updates which were quicker. I guess for the next MAJOR upgrade, i.e. going to the iOS 8 version that a cabled connection would be best? Not sure? Dave
Many people recommend the cabled method for major iOS updates. I've use both. With the exception of the time I interrupted the cabled version before it finished, during one of the pause/restart phases, they all worked.
There probably isn't any speed advantage to a major iOS update. It's not a patch, so the OTA is going to have to download the entire file. On the other hand, if you have more than one iOS device
of the same model, the cable method will save you time. iTunes only needs to download the update once for each model.
If your internet connection is at all chancy, stick to the cable if you have a choice.
All things equal, I don't think it's going to make much of a difference. Apple's got most of the bugs out of the OTA method. Which is good, since quite a few of the newer iPad owners have never used iTunes.
