Like its European cousin, the HTC Trophy for Verizon, when disassembled, reveals a microSD slot, where a SanDisk Class-4 16GB microSD card resides. This should be helpful for the individuals for which 16GB isn’t enough (especially because it really isn’t 16GB, but rather a measly 12GB of space). Pop in a nice 32GB microSD (just make sure it’s certified/working), and go to town.
Instructions for disassembling the Trophy (was written for the Euro device but both devices are physically very similar).
NOTE: Disassembling the phone most certainly voids your warranty, and is also not for the faint of heart. But we’re all Power Users here anyway!
