Basically, I have the iphone 4 that is currently locked to the canadian network, bell mobility. but because i travel frequently between the USA and Canada, my objective is to access networks for both Bell and VERIZON from the same phone via differing sim cards.
i've heard that the wrap around antennea makes the iphone 4 a true world phone, but is this actually possible? how would i go about using the phone stateside and beyond?
Thanks!
