And you are here why?

Ya know that T-Mobile has been repurposing its old EDGE frequencies to allows HSPA (i.e., fast access to the inter-tubes), right? And that this means that in some areas, you can get on T-Mobile at 1900MHz, right? Instead of needing to do it at 1700MHz, right? (that last bit is important - it means you can use most "world-phones" instead of "T-Mobile only" phones) Herewith a handy-dandy map showing you where people have been spotting the repurposing .  The short version? In a bunch-a places, but not everywhere...)

There are (essentially) two types of mobile phone networks out there in the world GSM, and CDMA.  For the purposes of this note, CDMA is Verizon and Sprint , while GSM is Everyone Else In The World, or at least, The Parts That dieswaytoofast Cares About Right Now . As you might guess, I'm going to ignore Verizon and Sprint ... Within GSM, we have both " 3G" and " 4G" services.  Again, lets ignore the point that what everyone claims to be " 4G " service is actually not 4G service (theoretically), but what the heck, its faster than "3G" , and thats good enough, right?  Basically, from now on, "3G" means "slower speed", and "4G" means "higher speed". Anyhow, all these services run on frequencies that are all across the board. To over simplify this, we have the following (all frequencies in MHz) 3G Service North America ( Canada, Mexico, USA ) - 850 & 1900 Most of Central & ...
