This whole microSD/expandable memory thing is pretty crazy. As we've heard, it depends on if the carrier supports and endorses such behavior, as well as if the device has access e.g. Samsung Focus does, HTC surround does not.

Now we're hearing from T-Mobile in an email received by one of our readers who asked. In short, replacing the memory on your HD7 will void the warranty. Now for some, that's not a big deal, but others it is something that you should at least beware of before you commit to upgrading the storage card.

Thank you for your interest in T-Mobile and the HTC HD7. Please be advised that the HTC HD7 is equipped with 16 GB of internal memory. Any attempts to modify the device would result in voiding the device’s one-year Limited Warranty.

If you have any questions, please do not hesitate to contact me via email at

Very truly yours,

We just sort of wish everyone was on the same page here as mixed messages will cause confusion.

Thanks, AtomicAgeZombie, for the tip!
