How's T-Mobile in SoCal?

[1badsup]

I'm thinking of dumping AT&T and switching to T-Mobile. How is the coverage in Southern California - LA and San Fernando Valley area?

Is it better to buy from T-mobile online, T-mobile store, Apple store or retailers? The T-Mobile online sales rep told me that they have a better deal if I bought the phones online. I know he's lying and I'm not quite ready to switch yet.

What do you guys think?

It's ok att has way better data speeds than T-Mobile but you can't beat unlimited data
