Almost has me considering an Evo since 4G is online in Austin already. It's a shame I can't just try out an Android device to see how it would really fit into my setup. Not willing to port my number to another carrier and buy a device without some hands on time.
Does anyone know if it's possible to port a number over after you've already been assigned one by the carrier? Seems like it would be feasible to me, but I don't know about these things. If so, and if Sprint has a return policy, then you could forward your iPhone's number while you try it out. You wouldn't be able to call from that forwarded number, but it would at least be a way to test it out. It's not convenient, but it's something...
