Should I unroot for AT&T update?

[blackdogAC]

Searched but didn't find specific info.
AT&T sending update out. I'm rooted so obviously it won't "take".
1. Anyone aware of what the update is and if it's worth it?
2. How does one go about unrooting to enable an update?
3. Will towelroot work again AFTER an update?

thanks.

No, it'll stop at the "is this phone rooted?" point.

1. Anyone aware of what the update is and if it's worth it?

Not aware of what it is, because I haven't seen it.

2. How does one go about unrooting to enable an update?

It depends on how you rooted. Most rooting programs leave little signs behind. The surest way is to flash a stock ROM.

3. Will towelroot work again AFTER an update?

As long as the kernel date is prior to June 3, 2014, so probably not. (Which is why I'm still at 4.4.2 and won't update to anything else until there's a rooting method and Safestrap or equivalent for my phone for the update.)

Does AT&T push out updates constantly if you area "out of date"?
In other words, if I unrooted two months from now, will they push the most recent update out to me then?
