depend on what games from xboxlive are u willing to pay.

1.  by changing storage capacity of ya HD7 will sure void warranty.

2.  "data" stored in phone after take out can not be read by any other device. u must use a special format to format the card in order u can use it back as normal microSD card again. this is what they called protected SD card whereby only certain brand of microSD card manufacturer has it. same thing to 32GB microSD card. not all 32GB works on HD7

not all sandisk microSD card work. once u have replaced the new SD card. your have to do a factory restore of the device to factory default. this process also will help convert the new microSD card to protected card which will only be able to read by that device only.

then ya device will ask for reboot. once the device reboot. everything will be alright.

please make sure u use the right microSD card. or else you might bring yaself in trouble because your warranty will void once u open any screw. and also make sure you used the correct screw driver to open up
