OR..
You could go and install Google Sync? Allows you to sync your contacts & Callenders to your gmail account
Been using it on my bold, and it works perfectly. Once you install it, just set it up (username + pass), and it'll even automatically back things up for you, so no need to keep remembering. Very helpful when ur doing a full wipe, and u dont have ur contacts
P.S - Works fine on 5.0.0.238 as well.
