From what we’ve seen HTC HD2 and HD7 only took SD cards up to 16GB so we tested and the HD2 works perfect with Windows Phone 7 and 32GB microSD cards.
All you need to do is to put the 32GB card in the phone, reboot and go to – Settings > About > and click on “Reset your phone” after the reboot you will have the card working 🙂
I do with a 16GB TOSHIBA microSD HC card, and don’t work. My HTC always is rebooting :S.
Can you help me?
