rookieatbest,
As one of the techno-nerds I met while shopping for a new phone put it, "In January your old phone essentially becomes a paperweight." I might add that it's not all that good for that purpose, either. Or at least mine isn't, since it's pretty light.
Sorry to put it that bluntly, but I feel your pain. Would have happily continued to use my 2010 model, but the march of technology prevented it.
The next question is how long 4G will exist....
