Hey guys, I was under the impression that since the DHD is quad-band, despite being purchased in Thailand I would be able to use 3G/4G , basically something faster than Edge when I came back to the U.S. Unfortunately this is not the case, could someone please explain why? And if there is any unofficial way to make it work, please pm it to me or at least a link. I have searched the internet but being a previous Symbian and iOS user , I am not at all familiar with the way Android phones and their various software iterations and custom firmwares function. Thank you for the help in advance!
