The description I am about to tell you is on the V3690, the V3688 successor. Theres no other category for it to go!
The Motorola V3690 is in my opinion a great little phone. It weighs only 82 grams, and has many useful features such as voice activation, silent vibrate and a large capacity phonebook. It comes in four colours, blue titanium black and champagne. The titanium model looks the best in my opinion. The later models of the V3690 also have the useful feature of predictive text input, which nowadays is a necessity for all enthusiastic texters. The V3690 also has a voice tagbook, in which the user can record voice notes for up to 2 minutes. This function is very useful.
Similarlarily to the Ericsson T28, the Motorola V3690 has an active flip, and if you are after a small phone with many great features, decide between these two.
One major disadvantage is that the menu takes some getting used to altough once you are used to it you will be fine.
A very desirable phone, which will make you the envy of many of your friends!
Now the price tag is about a tenner on contract, I really would reccommend this phone, as I paid £220 for one and I was happy with it .
