Since last upgrade, OS update 8.0.10501.127, old problems are back, HTX 8x can't recognize SIM Card, Can't open PDF from email, Can't open .WAV file from email and Can't share internet with Surface 2. All of these problems existed when I purchased this phone from Verizon. However, over time, these common uses of the phone, which by the way worked flawlessly in prior versions of Windows Mobile so this is not cutting edge technology we are talking about, began to finally work after various updates were installed.
But since OS update 8.0.10501.127, all the above problems are back. Please help VZW. Do I roll back the last update? Is that possible? Are you ever going to release 8.1 that you and HTC have been sitting on for almost a year?
