I'm also with Sprint and need a new phone. I took a long look at the new Samsung Instinct. It's similar to an iPhone in many ways. I was impressed but I'm going to wait just a bit for some reviews to come in.
Oh dang, dude! Maybe you'll find it when my ban is lifted...hahahahahahaha
Remember, you can go to Sprint and get a really good phone for free or super-discounted, and stay on the same plan you are on now. And when you do, activate the "Family Locator" service....it's $10 a month, but you can look up the location of your phone on line any time you want. I've lost my phone twice, and found it (both times I left it on top of the FJ at work, then drove off and it fell to the dirt lot) after using the locator. I love that thing!!
Next time we hook up I'll show you how it works. It's really cool!
