A dumbphone with email access?

The Kyocera Wildfire would be pretty good for that. I used it with Virgin Mobile, which is Sprint now. The Qwerty keyboard was especially nice for email.

i have an http://www.lg.com/us/cell-phones/lg-VN251-cosmos-2 phone (on verizon, but i think it's sprint-compatible too). the phone is fine, nothing to call home about, but it does have a flip-out qwerty keyboard. on verizon i pay just $4/month for "data" and use it to check my gmail 1-3 times a day. that i do through the phone's web browser, not through any sort of email app, so i have to log on every time; the phone doesn't tell me if i have new email all by itself. i find it to be a nuisance for actually responding to email, but i imagine you'd get adept if you did it regularly. it's a great cheap way to have the security of being able to check and access email from anywhere.

You're only as connected as you want to be. If you don't want Facebook, Twitter, Foresquare, etc on your phone then don't install them. Or if they come with the stock configuration, don't configure them. Problem solved!

The http://reviews.cnet.com/cell-phones/kyocera-brio-gray-sprint/4505-6454_7-35004027.html is a Sprint feature phone with a full keyboard and web-based email, but would probably work to curtail your internet use in the same way as an old Blackberry would (slow, frustrating browser, small display.)

Depending on your email usage, this may not be featured enough for you: You can send and receive email messages via SMS (the text messaging protocol). You can send text messages to an email address and receive emails-via-text through http://www.accutracking.com/sms-email.html.

I have a Sprint Palm Centro that would probably do what you want. I'm not sure if you could get a limited plan from Sprint anymore (the Palms didn't require the "Everything Data" plan when I had it...I've since upgraded to an Android for more features). Are you looking to save money on a monthly plan or just block all the extra web stuff?

I used an LG Rumor (the original, not the Touch) on Sprint for quite a while. I could do little more than email and text with it, but it did both of those things pretty well with it's slide out keyboard. It looks like they're going for about $50 on eBay right now.

I'm just trying to block all web stuff--this is yet another version of the ubiquitous AskMe "help me not waste so much time on the internet!" question--I actually have unlimited data on Sprint already, but am both trying to eliminate distraction in my life & streamline (I rarely use the internet-on-my-phone in useful ways, whereas I do get productive internet work done on my laptop). muddgirl: I'd totally forgotten about that! I haven't used it since 2004. I get far too much email to use it reliably, but it's good to remember! I kind of already asked this above, but am still curious and it hasn't been answered yet: could I have Sprint block all email except access to the gmail app (or some-such port-specific thing)?

i currently use a samsung reclaim from sprint which they gave me when another phone i had crapped out. it's in a blackberry style with a full qwerty keyboard. if i close one eye and wait five minutes i can use it to surf the web but overall the performance there is so bad i don't bother. i could also easily remove all the apps that have web access. i think it would fit your needs very well.
