Hello brad560, and welcome!
On your myTouch there are actually various ways to backup your contacts. If you are interested in having them backed up to T-Mobile.com, we need to ensure that the built-in sync is turned on and the contacts are stored to the 'T-Mobile' catagory on the phone. To ensure sync is on, do the following:
To activate Mobile Backup, follow these steps:
- From the Home screen, press the Menu key.
- Touch Settings.
- Touch Account & sync.
- Under Manage accounts, touch T-Mobile.
- Select (turn on) or clear (turn off) the check box for Sync contacts.
If you then want to copy contacts from the 'Google' catagory to the 'T-Mobile' catagory, follow the instructions in the link below to first move your contacts to the SD card, then to import them to T-Mobile.
I hope this helps!
I would avoid using any other contact backup other than Google. It's not that there are issues using T-Mobile contacts, just what happens if you change carriers, or you've got some contacts in T-Mobile and some in Google, or any number of other unnecessary headaches? Google takes care of contacts very well, there's no need to complicate things further.
