Hi guys, I live in an area with non-existent T-Mobile service. I tried switching to them before but I'd only get one bar outdoors. Anyways, I'd really like to get the Nexus One and use it with AT&T, which has great coverage in my area, and I was wondering if I can cancel the T-Mobile plan after a month and avoid the ETF based on the coverage (which still shows on their website as having good coverage in my ZIP). I saw something about a 120-day return policy, instead of the standard 30-day one, so I wasn't sure. Thanks!
