One button-press phone call recording
…isn’t such a novelty. My trusty, old siemens s45 offered that feature. My nokia 7650 also offers the possibility to record phone calls, but it’s not quite as simple and comfortable as it was with the siemens s45. Actually i never used that feature, though i can imagine that it could come in handy when "negotiating" with telephone support about important stuff. Just make sure that the person on the other side of the line knows that you’ll record the call.
