Proxy or Aircard For Mass Mailing

Is an aircard useable for mailing with 1000s of h0tmail accts? As opposed to getting thousands of private proxies?

i would say Air Card

Go with the Air Card, i use my iPhone for mass mailing and inbox rate is excellent. It uses the same IPs as the AT&T 3G Card. Just make sure to rotate your IP. See thread here for info on using iPhone as an aircard: http://www.blackhatworld.com/blackhat-seo/proxies/140918-how-get-unlimited-fresh-ips-your-computer-using-iphone-tethering.html

Are there any aircards that are actually $50-$60 where I don't have to sign up for a 2 year contract? The only ones I saw without the contract cost over $100 and I'm rather poor right now
