The 3G-enabled LG Viewty, otherwise known as LG KU990, is now getting an EDGE-only version - the LG KE990.
The LG KE990 is a variant of the LG Viewty (LG KU990) which has all of the same features mentioned above with the exception of HSDPA support and instead packs GPRS/EDGE, dual band (850/900 Mhz) support . In the LG lineup, the first two letters typically define the network support, KU is reserved for 3G UTMS/HSDPA phones while KE notates EDGE data support.
To add some icing to the cake here for T-Mobile USA customers, the FCC approval documents are available for the LG KE990 which defines two other editions: LG KE990c and LG KE990d.
