My son is after a new phone and wants one of the Sony Ericsson ones. So I've been looking around and I really like the 910i and I think he will like it.

I saw it on the weekend for around 90 on PAYG which isn't too bad so my questions are :

1. If anyone has used these handsets are they any good?
2. What alternatives are there?
3. Where can I get one from cheap (I'm on a budget!)
