I have the Sanyo 4900...from Sprint. My favorite feature used to be the speaker phone...although I don't know the last time I used it!

But I think it's durability is it's best feature...you can drop it on concrete, down stairs, in water, etc. 50 million times and it keeps on ringing!

Matter of fact...I dropped it this morning!

Gotta love the 'break away battery'! LOL!
