Mystery icon in status bar after OTA update to 2.3.6 on Samsung Charge

I've been searching for the answer to this and my guess was it is the symbol for a network extender. I haven't found anything conclusive yet though.

 

my husband got this on his charge too. we have decided that it is the network entender because it only shows up at home, not at the office or while driving down the road. (the other option would be that web connected samsung bluray player we recently got but that seems a bit far fetched)

 

I have the same icon on my phone appear randomly when I am at home and I do not have a verizon extender. I have also noticed this when I was sitting in a vacant parking lot eatting lunch one day. I have been trying to figure what the icon could mean.

 

You may not have a network extender but one of your neighbors may have one your phone is picking up.
