Related ot the phone being off? I'm not sure what you mean by that. It just seems to happen anytime, randomly.
The phone does turn off wi-fi when sleeping, there is no option to override that either.
HD7 on T-Mobile. I've noticed it seems at times, even if I'm connected to Wi-Fi, the phone still uses the cell data connection instead. If I go turn off cell data, it will then use wi-fi and everything appears nornal.
Anyone else? Known bug?
