currently have a Samsung Caliber on U.S. Cellular. it is by far the worst nightmare of a phone/service i ever experienced. it has not worked from day 1 & the customer support 4 it is irritating beyond belief. they said it has 2 b sent in 3, count it 3 times b4 they replace the thing & im paying $100+ a month on unemployment. as soon as the white iPhone 4 comes available, im canceling it w/o a doubt.
