I have Verizon and live in a dead zone, no service anywhere. my friend has t-mobile and gets service bc his phone connects to wifi. new blackberries for verizon have wifi, if i get that phone i know i can access the internet in more areas, but will i get better cell phone reception? i'm tired of having to walk out of my house to make a phone call. i heard wifi will give you cell phone reception. help please!
