I decided to open up this thread since D3 is a global phone that sports 850/1900/2100MHz WCDMA and quad band GSM support for outside USA GSM/WCDMA carriers.
Much like Droid 2 Global it likely has the US carriers banned. Since we know how bad the situation with Droid 2 Global was with Verizon custom SIM locked handsets, I believe this thread will be useful for people who plan to use the phone outside US on a GSM/UTMS carrier.
I totally like the specs of D3 and seriously consider upgrading my D2G. For use in Canada primarily.
I, and I believe, quite a few others, will highly appreciate any information regarding the ways to SIM unlock the phone for use with other (non-US) carriers.
