My old W995 lay down and died after 11 years, I couldn't find a modern dumbphone with anywhere near the specs in certain areas so I opted for a used one off E-bay, it came in great condition but it's t-mobile branded and/or has an old firmware and doesn't support conversations in texts so all you have is an Inbox and sent folder to trawl through which is a pain. I was hoping it would be simple matter of upgrading the firmware to add this feature? I'm new to fiddling with mobiles so don't really know where to start. If someone could advise it would be much appreciated, cheers.
