i very rarely use a cell phone so i can't help you make a choice.
but i do have an interesting link about cell phones.
if you guys have kids that use them like most kids do nowdays,
you need to read this. these phones are getting more powerful and dangerous.
your kids are frying their brains away!!!

"First generation cordless phones operate at about 60 megahertz and the next ones ran at 900 megahertz--higher than 835MHz cell phones. The new 2.4 GHz is higher still and can transmit for several kilometers without fading. MICROWAVE OVENS operate at 2.45 GHz."
not only cell phones but your "NEW" cordless phones at home.
it's a long read but worth it.
KEEP THE KIDS OFF THOSE DAMN THINGS!!!
