Heres how I got my tracking number:
1. Log in to Sprint and click See my bill, then click order history on the right, copy your order number for your EVO 4G LTE (Should start with a DM)
2. Put https://myaccountportal.sprint.com/servlet/ecare?inf_action=orderLines&orderId= in your web browser, and paste your DM order number after the equals sign.
3. Get your account number from the resulting output.
4. Go to UPS.com and on the left where the tracking text box is, click more options, then click track by reference. Input your 9 digit acct number in the "shipment reference" box and click track (you shouldn't need to mess with any other options, just input the account number). That got me this..

Nice find. Sadly, My info screen that shows up has no tracking number.
