Hello! Can someone guide me on what kind of device I have to purchase in order to verify if a phone actually has a specific Mhz band (e.g., 900)? Many times with Tribands they list the specs on the web site or manual as \"900/1800/1900\" but in fact it turns out to be \"850/1800/1900\" (America version rather than European one) so I want to verify a sample phone before I commit to making a considerable purcharse. A very practical way to verify this would be to insert a local SIM and then manually choose a network for the SIM to register: A network of an operator that I know (by checking it on gsmworld.com) only operates under, let\'s say, 900 band... However, the problem is that where I\'m located the only operators are 1900. Best! Danny
