Looks like Nokia is testing the CDMA waters again, which I'm glad for. This time though, their phones are headed directly toward the recipients of the AWS spectrum, coming this fall: CricKet and MetroPCS. Or at least, I'm supposing that's why they have tri-band CDMA service with AWS capability.
On the one hand you have the relatively powerful 3606. With MicroSD support (including cards as big as 8GB), a 1.3 megapixel camera with a flash, stereo Bluetooth and a snazzy hidden external display, this little flip phone is a welcome addition to teh high end of CricKet\MetroPCS's lineups. Sure, you can get the Razr2 on CricKet but the Nokia will probably sell for around $200 and packs enough features that you won't miss the Razr2. Plus, Nokias are just awesome phones.
On the other hand, you have the much more basic Nokia 1606. No camera, no Bluetooth, no memory card slot and the presence of a flashlight indicate that this is probably a phone in the $100 range, maybe a little more expensive, but not by much. It's not such a great phone feature-wise, but hey, it's a Nokia, and with both low-end and high-end phones coming in the fall I'm happy.
