What is the cheapest way to get wireless internet?

What is the cheapest way to get wireless internet?
I need wireless internet only to do things like check emails, and get on craigslist, and ebay.
What would be the cheapest way to achieve this. A cell phone? Ipad? and what service should I use Verison? Cricket?
Thanks for any info on this.

Mod Note.. This Topic has been moved

I bought a blackberry (curve 8520) off a mate for £50.
Im on O2, pay as you go .. but i've attached a 'blackberry bolton' which takes £5 a month off of my credit, giving me Unlimited Internet usage as well as blackberry perks such as BBM (blackberry messenger) - which is free text, voice, video, picture and file messages to other BBM users.
You wont have access to the bolton unless you have at least £5 credit on your phone.
The service supplier will send you a text a few days before you're due to pay.

If this seems confusing, there is a help number which i called and they are very friendly and very helpful. They seemed to know blackberrys like the back of their hand.

The internet service is often very good and blackberrys are also wifi capable, meaning you COULD find a sneaky connection if you're in civilisation!

I really do hope this helps.
