If you have a BlackBerry on AT&T, you may want to check out their new app released to keep you up to date on your wireless account. myWireless gives access to your bill, usage details, and your devices's current and available features. You can even break it down by phone number if you have an account with multiple lines. Hit the jump for details and link to mobile download.
Bill & Pay
You can view the current amount owed on your bill, as well as make a payment. myWireless gives you all the same options as paying online or by phone: Previous card used, new checking/savings account, and new credit/debit card. I personally tested this out paying my current bill today. It was very fast, taking only 5 or 6 minutes. It would have been even quicker if I would have used the same credit card that I usually use.
This section allows you to check detailed information on how many minutes you have used, as well as how many you have left. You can also view how many text messages you have used up on your billing cycle. For some reason they seem to have left out information on the lines mb usage for data enabled devices, not really sure why.
In this section you can add any features that are available for the selected line, such as BIS service, text messaging, and tethering. Unfortunately you can not remove current features associated with your account, for that you will have to login to your account via PC, or call AT&T directly.
Overall I think this is a very convenient application, giving you quick, easy access to your AT&T account. I have found that AT&T's online account access has always been extremely slow, taking an unusually long time to access each page of your account information. Because of that, I think I will stick with the myWireless app for the most part.
