I think so Motorola DROID A855 Android Phone (Verizon Wireless) is the best for your husband.In this phone you can be able to use facebook,email, navigation, web browsing.It has a big touch screen and may be it's price is under your budget.

We recently upgraded my phone, and in doing that, had to sign a new 2 year contract for our family plan w/ T-Mobile. That was 2 weeks ago and now my husband has decided he wants a new phone as well. WE called and he was told he is not eligible for a phone discount now because we just did an upgrade to get my phone discount. Anyway, we are very frustrated because his phone is now not charging. He has my old phone which is a Gravity T and now wants a smartphone. Since we cannot get a new phone at a discount, I am looking to get him a used phone. I am looking on Craigslist and trying to research T-Mobiles phones. My budget is around $100 and these are the options I have found that are in really good condition and in my price range:

Samsung Galaxy S 4G
Samsung Galaxy Vibrant
Motorola Defy
Samsung Exhibit 4G
MyTouch 4G
MyTouch 4G Slide

He mainly will use it for email, navigation, web browsing, and Facebook. He wants a bigger screen than the Gravity T.

Are there other used Smartphones that I should be looking for as well under $150? Should I rule any of these out? Is there somewhere else I should be looking?

Thanks!
