But Claro is NOT GSM service...
BUT it was stated is that the Verizon Iphone 4S can be Programmed to work on the ORANGE network (GSM). ?? .. which i never heard before..
Can someone verify this..
Just cause your phone has a Sim Card, does NOT automatically make it compatible with GSM service..simply by unlocking it..
GSM and CDMA are completely different systems
and when people says 3G and 4G... well thats just "generation" (by the way the "4g" foot print is not even complete yet eventhough the Market It heavily) , it has nothing to do with GSM VS CDMA
the old TDMA was 2nd generation I believe , , and Analog was definitely the 1st Generation...
or did i read that incorrectly..
and yes I used to work in Wireless, but NOT the Tech end of it, back when GSM was BRAND NEW in the USA .. so its been a while, so i could be wrong.
