shoeless
Riffin'
I just did the same thing about a week ago. I kept waiting for my S3 to die, but it wouldn't. It got pretty finicky about what charger it would accept, but other than that it worked fine. The gal at the cell phone place laughed at how old my phone was.I went from S3 to S7 and it was a huge leap.
I bet those old Nokias would still work if the network supported them.
I picked up this piece of old technology at a yard sale for $2.00 a while back. I spent almost that much on batteries for it, but it works flawlessly.
