The reason it says to check back in 20 hours is because AT&T doesn't like people checking more often than once a day for updates.
Thanks! So even though the update is available, I hadn't gotten the bug fix yet, so it only allowed me to get the bug fix instead of the update? Theoretically then, I should be able to install the update this evening then, right?
