Morganator,
As deggie already pointed out I am agreeing with you. I am also disappointed about the change as well. Apple takes the feedback they receive through those forms seriously and it was quite apparent that users were dissatisfied with the length as they were. I would say the old phrase "you just can't please everyone" but in this case I really do think you can - just let us choose our own and provide both sets of lengths 🙂
Updates are supposed to bring features and improve the user experience and that's not what's happened here. If only I could revert to the previous version...
I am sure to some users they do consider this as an improvement to the user experience. You often don't hear them though as few come to these forums to praise the improvements as they are already satisfied. The ones that do, like you and myself, post with new problems such as this. If you are really truly devastated and want an immediate solution, there are ways to revert to an older iOS version that you may find somewhere online- but be very careful as it is totally unsupported and extremely risky.
