I upgraded to an HTC s640 from Telus Mobility in Alberta Canada. Before I was running a Moto Q with WM5. I installed the new activesync which came with my new phone, everything went great. The installation was smooth, and it successfully syncd up my phone with Outlook 2007. About 2 weeks after I got my phone, unplugged from a successful syncronization and my computer (laptop running 802.11g WIFI) basically froze up and I had to restart the computer. After the restart, I couldn't connect to the internet wirelessly. Not only that, I can't even connect to the wireless router with my HTC phone! It completely disabled the router.
