FYI, the 3125 is no longer available in the Cingular stores, only online. My guess is it will be disappearing from there before to long as well.
My understanding is that the 3125 will not be getting the upgrade to Mobile 6 either.
As a 3125 owner, all of the above is extremely frustrating. I bought it new this past September to replace my old MPx220 (which I'm one of the few people who liked it) as I wanted the new O/S and a new phone. I didn't think 8 months later I'd be in the same boat. Especially, when I had to sign a 2yr contract to get it at a decent price
To make matters worse, I've discovered one real pain in the neck design flaw with the phone. It has a micro switch inside that shuts it down whenever the battery cover is removed. Well, about two weeks ago the cover started slipping a little whenever I pulled it from my pocket and sure enough a slight shift and I'm dead in the water <sigh>. That's how I discovered the 3125 is no longer in the stores and being slowly phased out as I went in search of a replacement and the employees did their best but there's nothing left. So now it appears I'm going to have to find a way to tape it shut, YUCK!!!
Sorry for the diatribe. As I mentioned above I REALLY like the phone, but with the above issues, I wanted to get the word out so people were aware prior to taking advantage of Cingular's offers on it.
