I just purchased the U300 and installed Sprint's SmartView software. No problems accessing the Internet.
However, when I launch the E-Trade Pro Java application, I am only getting partial data throughput. For instance, I can see the stock symbols and accurate graphs, but the stock prices do NOT display. When I switch back to my home's wireless network, the E-Trade Pro application works fine.
I uninstalled/re-installed the SmartView software. I even cleared out the Java cache. And the same problem persists.
Any recommendations would be quite appreciated. Otherwise, I may have to return to using my Verizon mobile broadband card (which did allow for E-Trade Pro to function properly).
