In February 2007 I ordered with a contract extension, the Nokia 6131 and was already after a few weeks disappointed by the device. Although the design chick and the keys are a good size, but the performance of the phone is hardly worth a star. First, the battery lasts not long, I need to go super notice often that I have no power in the battery again. This is it every other day to end without having phoned for hours, I still happens in any phone before. For this, the acoustics when telephoning is often quite poor. I also think it's annoying sms write that it has little space for the "own dictionary" in the T9 predictive text input
Meanwhile, I am actively looking for a replacement device, so very disappointed I am by the acquisition of this phone.
