http://www.straighttalk.com/ There are some excellent prepaid cell phone alternatives available! Straight Talk is definitely my favorite - this is a Straight Talk commercial I found.
They even have android handsets - I have a Samsung Galaxy now!
Two plan options: pay $30 for 1000minutes + 1000texts + 30mb data OR
$45 for unlimited everything. The android handset is only available on the UNLIMITED plan.
