I am creating a spread sheet to show what carriers the droid and milestone are compatible with. I dont think anyone has done anything like this yet. I am having a hard time finding what bands foreign carriers use because I only speak english. If anyone would like to contribute to the spread sheet or see any errors it would be really helpful so make a post. Right now I am working on the following carriers 3G and GSM bands. USA AT&T Verizon T-Mobile South America Claro TIM Germany O2 Vodaphone And any other common carrier in a the countries the droid/milestone is released in. Since I cant upload a .xlsx file I attached a picture of the spread sheet. I also uploaded the spread sheet as a .doc file, to open it you will have to rename it to a .xlsx file. I updated the picture but not the spreadsheet.
