Need new mobile phone - any recomendations?

[TracyK]

I'm going from Vodafone onto Virgin and would like a nice new phone.

I need to use it with Bluetooth - so no echo would be good.

Don't really care about MP3 or photos though.

Up to about a hundred quid.

Not sure about specific model but I used to work in the 'handset faults' dept for orange and found sony ericssons to be the best/most reliable/easiest to use phones hth
