Text messaging is also easier, thanks to to the T39m's T9 Predictive Text Input software. This reduces the number of times you need to press a key on the keypad to write a letter by choosing from a dictionary of words and phrases and anticipating what you intend to write. 

Feature-packed and aesthetically appealing, T39m is for people who want performance. 

Advantages:
Fabulous value for money, nice size, feature packed, great choice of accessories. Great battery life.

Disadvantages:
Display could be bigger, but by reducing text size you can still get 5 lines on the screen at once. Ericsson still not quite as straightforward to use compared to Nokia, but really this is nitpicking what is otherwise an excellent phone.
