[T-Mobile Samsung Galaxy S II SGH-T989] Docmjldds:
I have used Quickboot since my N1 days. But...quickboot will typically NOT work if your setup has the shutdown or reboot issue. I know this because until I had tried the cache wipe, dalvik wipe and fix permission shuffle, Quickboot hung also on my setup. If it worked for you...that's great. But it didn't work on my setup. I would think it's basically making the same means to enable the shutdown or reboot. Just basically a different menu that achievers same function. I could be wrong on how it works, but I know on my setup it didn't work. For any user here having the issue, try going to the market and download the app. Side bets and if it works??? :)

+1 finally. I posted the TMobile FAQ for all to see. There is erroneous info going around here. Users have to call customer service to have this added to their plans or it WILL go against minutes, based on the specific plan they have. Before anyone flames me on this, read the post from me with the specifics I cut and pasted from the TMobile web document on the My Tmobile site. It's is totally free, but customer service must add this specifically to your plan..

Here it is again:

Billing

There is no additional monthly charge to use the Wi-Fi Calling feature on your handset.

Wi-Fi Calling uses monthly plan minutes for the following:

Calls made from the US to US numbers

Calls made from the US to international numbers (subject to international rates)

Calls made from outside the US to US numbers (not charged roaming)

Calls made from outside the US to international numbers (subject to international rates, but not charged roaming)

Note: You must disable Data Roaming when travelling internationally to avoid incurring data roaming charge

Free Wi-Fi Calling can be added to Even More and Even More Plus plans for unlimited calls over Wi-Fi

Sign into MyT-Mobile.com to add this feature to your account.

With the Free Wi-Fi Calling feature calls made over Wi-Fi will not use monthly voice plan limits. <<<<<<---------You basically should call customer service for this

Experience

The Wi-Fi Calling widget cannot be downloaded from the Play Store. If your phone is Wi-Fi Calling capable, you will find the Wi-Fi Calling feature in the application tray of your device.

Select the Wi-Fi Calling widget and then select the On/Off toggle button to activate/deactivate Wi-Fi Calling. Follow the prompts to connect to a Wi-Fi network, if necessary.

There is no handoff between Wi-Fi and the T-Mobile network. If you are on a call and are reaching the edge of your Wi-Fi network, you will hear a tone as well as receive a pop-up message on the display warning that the active call will disconnect. Move back into range of the Wi-Fi network to complete your call.

If multiple devices (laptops, desktops, other cell phones, etc.) are sharing the same Wi-Fi signal, then device performance over Wi-Fi may become slow or unreliable.

Device requirements

Wi-Fi Calling is available on certain Android devices; check the Tech Specs for your device for more information.
