The other cell phone thread got me thinking about an upgrade as well. I don't think I'm going to drink the iPhone Kool-Aid, so I was looking at another Nokia flip phone. The one I've got does everything I want it to, and it's especially good at making phone calls. In my opinion, this is a key feature of a good cell phone. The new flips have more extraneous features geared toward 12 year old girls (music player, Facebook/Twitter capability, crap like that), so I'm toying with the idea of picking up another Nokia 6126 off of eBay. Yes, I'd probably spend a little more money than if I upgraded through AT&T, but I wouldn't be bound by another 2-year contract and the phone would be a known quantity (rugged, compact, email capable, easy to use).
So, if I go this route, will I be able to swap my sim card to the new phone and get on with my day? Other than not having the "latest and greatest" technology, is there a downside to this? Anyone have any firsthand experience with this?
