Install HTC Sync.
Plug in Phone.
Unzip the update file.
Run update file.
10 minutes later you have 2.1.

Read the page you downloaded from for a bit more detail or look at the readme that pops up as you start the update.

 

Hook up your phone to your computer through usb and then double click on the exe file

 

Get the newest sync program here if your having trouble downloading from HTC:
MEGAUPLOAD - The leading online storage and file delivery service

Edit: Good link

 

The latest version of Sync is 2.0.33...that one is listed as 2.0.28.

The latest version supports Windows 7 x32 and x64 for those of us who needed it. If you are running XP, you should be fine with 2.0.28

 

Your right. Oops! Edited for the right link!

 

Im guessing since everyone is on HTC downloading it is why its going so slow, but for us lucky ones we have great folks to help out.....Gotta love this forum sometimes

 

I must be in the Twilight Zone. I downloaded my RUU from Sprint's download site after failing repeatedly to get a complete download from HTC. I extracted the exe from the zip and connected my phone. (HTC Sync already installed and running.) I get a window saying that RUU setup is preparing the InstallShield wizard that will guide me through the rest of the process. The window disappears, then nothing. No other window pops up, nothing unusual seems to be running in Task Manager. Nothing happens after the initial window asserting that InstallShield will run. Anybody else experience this?

 

It had something to do with Vista, apparently. The behavior I described was on my Vista laptop. On my XP desktop the installation went fine.
