Does anyone know what they are actually changing? Now there are a lot of 2G Edge towers that use 1900Mhz, lots of slow speed UMTS 3G 384Kbps towers using 1700 Mhz and a few high speed 4G 24Mb towers using HSPA+. I wonder if they are going to convert all the 3G and 4G 1700 Mhz towers to 1900Mhz or just the the 3G or just the 4G towers to 1700 Mhz? There are about 50 towers withing a 10 mile radius of me with most of them being 2G and slow speed 3G but only 4 of the high speed 4G towers that I can find. If they convert all the 3G and 4G towers to 1900 Mhz there will be very good coverage everywhere and if they convert just the 3G towers there will be pretty good coverage but not everywhere and if they convert just the 4 4G towers to 1900Mhz the coverage will be terrrible! On that map it shows just ONE 3G tower on 1900 Mhz in my area and it's in the location that used to have one of the 4 4G 1700Mhz towers. On the other hand the guy who made the map is located in Germany and doesn't really seem to know how the American phone system works so it might not be accurate.
They must have just put up a new tower near me because when I turned on the Galaxy S yesterday I was getting 4 bars with 4G! I tried to use OpenSignalMaps to find out were the new tower is and it shows one just a couple of blocks away that wasn't there before but couldn't give the exact location and it doesn't show up on the German airportal map. Also it's on 1900Mhz band 2 which is what they are switching the older 3G service on 1700Mhz over too. You might have to change the settings in your phone to get it when it comes to your area though. My Galaxy S-2 couldn't get it at first until I changed the band setting from Auto to WCDMA.
