Has it been determined if the issues with WiFi or 3G signal dropping a hardware issue on the device or a software issue? I have 3 days left to exchange it for a brand new one and it would defeat the purpose if it ends up being on the software side. I really love the heck out of my DX (52hr battery life with light usage!). But I'm getting sick and tired of either signal dropping randomly and not being able to connect on the Internet. I have to turn WiFi off/on, or with 3G, wait 'till it finally decides to reconnect itself again or close window and try again. When I do get a locked signal, it is fast, but within 10-15 minutes it drops. With WiFi I have tried many configuration with my router and everything is a No Go, same results. From reading other posts and forums, some people are not experiencing any problems at all with their WiFi/3G connections. So that makes it real difficult to say which of the two is the culprit. Hardware or Software?
