Maybe we have to connect our Windows Mobiles to our Laptops, connect to 3G, Share the 3G to the Laptop via USB, then make a Windows 7 Wireless HotSpot with the laptop's Wireless card, and connect the scroll to the Laptops WiFi Hotspot.
Out of interest, my Sony Ericsson X10 connects easily to my Scroll. In settings (on the phone), go to wireless & network & select "use as mobile WiFi hotspot", then, on Scroll, again go to wireless settings & just select the phone as the network. Works for me
as this is my first and only post here i presume the links will be modded until approved so just google for a blog called 'seeing and believing' looking for the links to the 'androidwifi' pages on seevisionc dot blogspot dot co dot uk
