Back during the dog days of July, PhoneNews said that the LG Esteem would be a version of the LG Revolution for the pre-paid carrier. There are some differences, such as a reduced 4GB of internal storage vs, the 16GB inside the Verizon handset. The story fills out some more of the specs, mentioning that the build of Gingerbread on the phone will be Android 2.3.4. According to the PhoneNews story, the LG Esteem will be launched in the middle of next month which fits with the phone's appearance on LG's Partner Portal.
