Here is a thread with about 30 responses about tri/quad band phones from the last few weeks. People did tens to agree that Motorola sucked. I'm still in a holding pattern on what I am going to get until I find out for sure if Safaricom in Kenya uses 900 MHz only or if they use 1800 MHz too.Most of the tri-bands do not have 900.
