boost uses iden which isnt that widespread and tmobile uses gsm,

gsm(cingular, tmobile) and cdma(verizon, alltell, sprint) have more coverage over the us.

you can roam w/ cdma and gsm(contract)
with iden, if there is no coverage, then you are out of luck

i would say tmobile would be the better choice, even though it is the same size as boost, since it's gsm, you can roam on cingular's network if ur in a contract

i hope i didnt babble too much,

Both companies have smaller networks but are the size and call quality the same or different?
im curious

Yes, the difference is real. Not fake.
