OK, sorry I misunderstood. The first time I restored my original backup I got 4G back as well, but now it is gone again. I saw something flash on the screen that said "update"
and now 4G is gone. I was going to take my phone back to Metro today to see how easy an exchange would be before doing a RMA back to Samsung, but I can't find my original Samsung battery. Hopefully I find it tomorrow.
