Hope I'm posting in the right place. I've been noticing that when I want to download or update an app from the market, I can't do it with wi-fi, only 3g. Is this normal? Just asking because downloads would be faster with wi-fi.
I have the same issue, but it's extremely inconsistent. It's like my wifi connection at home has to grab a hold of my phone just right or it will act like what the OP is talking about.
