Yeah, the first 30 days are completely free of ETFs as long as the devices are in resalable condition.
check the signal from where you will use the phone. my brother just got he evo and he hits over 2.5 mbps through the day. on my droid with verizon i get around .4-.6 mbps. im about ready to pay the etf and get an evo.
I'm thinking about switching to sprint too. I like VZW for the most part but, like someone else mentioned, I can get my whole family on smart phones with unlimited everything for less than what I'm paying now for one.
Always consider coverage where you need it. Don't count on coverage maps. I've lived in areas marked as "good" with unusable to no coverage. Any generalized discussion on coverage is pretty pointless. You might want to inquire with anyone on Sprint in your specific area. Definitely use their 30 days (or whatever they offer) to fully test things out and make a final decision.
Sprint's coverage was, at one point, notoriously over-saturated. The problem was actually worse in big cities.
Maybe it's not that way any more, but 4G is also not very built out and 1st gen is going to be buggy.
IMO, if you travel a fair amount and need your phone to work all over the US then VZW is the only reasonable option.
I just got done checking cellreception.com looking at Sprint comments for my area (as I've been interested in the EVO too). Not very favorable. I've been around the block with just about every carrier (except Sprint) and come to appreciate Verizon. So EVO is out for me. On the other hand I know a number of iPhone users and they don't have issues with AT&T service. Still I'm not crazy about the iPhone maze of icons layout. I own both an iPad and iTouch and while I like them, I think the Android OS is better.....I just want it to be faster which I'm hoping is just around the corner with froyo.
