I live in Suffolk county on Long Island and work in NYC and was wondering about T-Mobiles coverage. I have 1 co-worker who has a T-Mobile account and loves it, however she has always had T-Mobile, for like 10 years or so and can't compare it to any other carrier.

I am on Sprint right now, and have no complaints. I've been on Verizon, and AT&T and all 3 have there dead spots and such so I'm used to that. usually its a dropped call here and there, nothing really big for any of those 3 but T-Mobile seems to be the least expensive of them all and I was wondering is it worth the switch?

Can anyone tell me what there coverage is like, call quality, data speeds, etc..? Thanks
