Usually '3G' is 'Third Generation', '2G' 'Second Generation' and is a relative reference, so the question is what does the carrier or manufacturer consider enough better to warrant a new 'name'. I always thought that they meant that the voice was better too, not just data... Well its not the first time I was fooled...

SIM stands for Subscriber Identity Module. So while the SIM card does or can contain your contacts list (eg, phone numbers), its primary purpose is to identify the SUBSCRIBER who is using the phone. Take your SIM card, put it in a different GSM phone, and the network still recognizes you and your phone number. If someone calls your phone number, whatever phone has your SIM card is the phone that will ring. if you place a call, the SIM card in the phone identifies who will get billed for the call. The phone doesn't matter. It is the SUBSCRIBER Identity Module (SIM) that identifies the subscriber who makes/receives calls. The SIM is actually a smart card. That is, it has a microprocessor and memory inside the card. It also has private keys that never leave the card. SIM cards are part of the 6000+ page GSM specification.

However, I do not understand how the bands listed indicate whether or not I will have AT&T 3G coverage. I understand that AT&T 3G uses 850 and/or 1900 for 3G. If I see a European model have one of those bands, is that sufficient, or do I need both? I also see bands distinguished between UMTS and GSM on GSM phones. Which matter for my purposes? Do I need just GSM? Both? What is UMTS anyway? Also, "another put in it’s place" -> "another put in its place" I am willing to buy from eBay an Android phone from another country so that I can use it on AT&T.
