I have a Sony Ericsoon T630.
Good things about it:
1) Ringtones (midis) don't need to be converted! That means that you don't have to use a PC program to convert the ringtone so that the phone can play it (unlike Nokia phones)
2) Ringtones (midis) play (almost) the same like when you play them on your computer!
3) Support themes, so it is fully customizable.
4) Included infrared Bluetooth and infrared.
5) Included camera
Bad things about it:
1) Has a bad camera.
2)
Has only 2 MB of memory!
3) Contacts are being saving in phone memory instead of SIM
I also had an alcatel 311.
Here's a pic of it:
Im not going to say the good and bad things about it, because i have time to use it, and I dont remember it
