Here is what I am finding with market errors, or connection errors all together. When I am home I have my wifi on all the time. When my phone is in sleep mode, the wifi turns off. When I wake it up, it takes a couple seconds for the wifi signal to show up in the status bar. AFTER it wakes up and the wifi signal is in the status bar, I continue to have problems with connections for about a minute. If I don't do anything but wait for a minute, my connection problems go away. But, the more I try to connect to things during the first minute, the longer it takes to connect. If I turn off the wifi, my connection problems go away.
