The Motorola Moto Maker is making its way, reportedly, to T-Mobile, allowing future customers to get the exact color option that they want for their Moto X. However, those who already own a Moto X on Magenta, and are feeling brave and adventurous, might want to check out this leaked Android 4.4 KitKat build for the phone.
You’ll have to have an unlocked boot loader in order to flash this bit, but, you should also read through the thread for feedback and impressions, because it really looks like a mixed bag. You can find all the instructions you need at the source; some issues with calls and data have been reported, but apparently a wipe fixes them. If you acknowledge all the warnings and you just have to have a taste of KitKat on your T-Mobile Moto X, check out the source link. If you unit is not a TMO device, be extra careful!
