I'm running an HTC on the at&t network. A few days back I had a huge update on the basic OS as well as nearly every at&t app on the machine. It took most of an hour to download and complete on wireless. Thank God I don't depend on the at&t data delivery. It would have blown the month's allotment.

OTOH, the new power saver function is fantastic.

My question - I now have a new icon grouped with the wireless, 4G, and at&t bars display that resembles a capital N or a lazy Z. There was no explanation as to WIH it is nor can I find anything about it online.

Anybody with a clue?
