My Windows Mobile phone, a Sprint HTC Touch Pro, slows my internet connection (6Mbps cable) when attached via USB (I have no bluetooth to test with that). It doesn't matter if the Phone is in Active Sync mode or Mass Storage mode, it slows down the internet connection to a few kB per second. I use a wifi connection to connect to a superg (108 MBps) network. Internet speeds are nominal when I disconnect the device.Any suggestions, tips, or help are appreciated.
