T-Mobile has released 2 new apps into the Android Market. The first one is Mobile Backup. This sync’s or backups your contacts with T-Mobile’s server.

That way if you lose your phone, you still have your contact with T-Mobile. This could be quite useful in case you ever get rid of the G1 for another phone where you would not be able to connect and sync your contacts with Google.

The other application released by T-Mobile is called HotSpot.

Now if I remember correctly there already was another app like this in the Market. Now you officially have one by T-Mobile is all. This app will find you T-Mobile WiFi HotSpot locations.

If you do not already have the app My Account by T-Mobile, then grab it already. They released months ago and it lets you check your minutes used, text messages used, bill summary, phone storage information and much more.
