Post this to see if anyone else has noticed these issues. This morning (after 3 weeks of use) I had my first battery reinstall event; Last night I tried to turn WiFi OFF and noticed the green bar on the utility dim. I went to Manage my apps, and found it was trying to turn off the WiFi (I'm at edge of my WiFi service at bed). So then I placed it on the dock, and noticed it sensed the dock, then locked up. Nothing would work. I was able to shut the screen off and go to sleep. In the morning I found it would not turn back on, until I reseated the battery. Also, when turned back on the weatherbug was frozen and would not update, so I had to power off and restart after waiting a minute. Now...all back to normal. I suspect, based on other issues below, that the devices was hung up in WiFi as I was on the edge of range for my router. Also, multitasking (dock) seems to have caused a lock up, while this is going on. Battery was at least half full, so not that. And, in general, I am turning WiFi on and off alot, and noticing it is abit sticky...sometimes wont turn on WiFi until I go to manage my wireless services. Not sure if this is due to having so many wireless routers in my neighborhood being sensed (eight at least), but when I go to management screen it starts connecting instantly. Seems like about half the time it is doing this. Anyone else noticing the WiFi issues?
