I just read a disappointing review of the Nokia 1680 on Steve Punter's Southern Ontario Cell Phone page.
While most of the other cellphone review sites are full of crap that basically list in their own words what the phone manufacturer lists in their brochure, Steven Punter writes great reviews of cell phones (as many as he can get his hands on) that focus on the real-life use of the phone, quality of the reception, sound reproduction, etc. You know, how good the phone is at making actual phone calls instead of listing a bunch of superfluous features.
Unfortunately, the 1680 did not fare too well. For those of us that were planning on eventually upgrading to a 1680 (like me), you might want to read this first.
