I am looking to purchase a smart phone. IPhone is out of picture due to contract obligations until mid-2008. Thank you!
And possibly longer. No one knows for sure, but I highly doubt Apple is going to go CDMA just for its US customers. It's an international company now, and they'll go with the international standard, GSM. They'll go unlocked or T-Mobile before they go Verizon or Sprint.
Oh, and the contract obligations are until mid-2009. "Multi-year" agreement is 2 or more years, 2007 + 2 years = 2009.
As for the best Sprint smartphone, that's your personal preference. I've used all of them. I did not like the PPC-6700 because the thing is freakin' huge, but some of my friends love the thing. It's a PDA first, phone second. Meanwhile, both Palms are designed to be phones first, PDAs second. That means expect less capability PDA-wise (no Wifi, Bluetooth 1.2, etc.) and more ease-of-use phone wise (tap a button and you can call a number).
I'd highly recommend the Treo 700p, then the Treo 700wx as a secondary. You can sync very easily for free using Palm's Hotsync software to your Address Book and iCal. If you go the 700wx route, you'll have to purchase a $40 program called "The Missing Sync" from Mark/Space.
Also, you can use both the 700p and 700wx has wireless modems. So, instead of getting a PC/ExpressCard from Sprint, you can simply plug in your Treo via the USB cable and connect to the internet. You get the same EV-DO speeds as an ExpressCard. You have to pay Sprint an extra $15/mo. for that, but it's better than getting a whole new line of service with a card at $50-$70/mo. It's a really great feature that sold me on getting a Palm.
Hope that helps...
