@Joe - some of the older modems (3g only) used in phones had issues reconnecting after being woken up and even if you selected it to stay connected the modem would still disconnect.
I don't know what the problem is. Phone is getting progressively worse. Will be returning it and have already opened a dispute on PayPal.
Definitely not discouraged though! Will be picking another one up until I get it right. Might see about going with a 5-inch 1080p the 2nd time around though. We'll see...I do love the 5.7 inch display though...
