[Closed] Mobile phone recommendation sites

I think my contract ends at the end of the month and I'm going to have to start looking for a new phone - existing phone is fine but it is almost 2.5 years old and I'm bored with it - does a perfectly decent job and still looks like new, but I want a change.

Are there any websites out there that allows me to put my existing phone in and then compare against the newer models?

I want Android and something 'better' than the Samsung Galaxy S2 that I have - decent camera would be handy, expandable memory and a decent battery life. However, I can't find a site that allows me to put what I want in as a list of requirements to then get suggested models back.

Does such a site exist? If so, where? Looking on the service provider's sites it doesn't really give a like for like comparison.

Cheers.
