I bought a pearl 8120 on ebay second hand.
It does most of the things needed apart from i am having trouble setting up the broadcast facility but am hoping to fix that by upgrading the OS.
You have to watch out for some who sell phones on ebay though as having purchased one from a company on there; when it arrived the speaker wasn't working but I did get a refund eventually.
The phone I bought was locked to 02..but I got it unlocked and am now able to use another carrier.
Have a look around and look for feedback scores.
