Official: myTouch 3G Slide OTA Update Rolling Out Tomorrow
Finally there is some great news for T-Mobile MyTouch 3G Slide owners fed up with poor battery performance of their phones. T-Mobile will start rolling out an OTA update tomorrow i.e. 4th August which will mainly address the poor battery performance as well as bring in some OS enhancements. This update will also allow you to send MMS messages when connected to Wi-Fi. Here is the official T-Mobile PR talk on this update: 
Beginning August 4, T-Mobile will send an over-the-air (OTA) update to myTouch 3G Slide customers, which will provide a number of benefits, including increased battery performance and enhancements to software features such as Faves Gallery and Genius Button. This is not an update to the Android operating system (i.e. This is not Froyo/Android version 2.2).
The update will be sent to customers beginning August 4 and we anticipate all customers will receive it by August 19. Customers will be notified of the OTA via a free SMS text message from T-Mobile.
The timeline for receiving the OTA cannot be expedited. T-Mobile will be unable to manually push the software to customers who ask to receive it before August 19.
Improvements included with this update are as follows:
1. Battery Life:
- Updates to the T-Mobile online contact backup connection, which will improve battery life.
2. Wi-Fi:
- Ability to send MMS messages when connected to Wi-Fi.
3. Genius Button improvements:
- Ability to turn GPS on and off using your voice, such as “Turn GPS on.”
- Will announce Caller ID for incoming voice calls and allow you to “Answer” or “Ignore” using your voice.
- Will announce incoming text messages and allow you to “reply” with dictation.
4. Faves Gallery improvements:
- The Faves icon will be displayed beside notifications that appear while the device is locked to indicate that the communication is coming from one of your Faves.
- Fave photo display speed will be enhanced.
- General stability will be improved, including more seamless scrolling and consistent display of photos
