$9.99 is for 25mb of use.... $29.99 is unlimited. The 3g phones have html browsers but process slower than smart phones. With the 3g phones you have the choice of $9.99 or $29.99. Smart phones do not have the $9.99 option. As Jones said they are like little laptops now a days. With either phone type you will probably start off surfing CR, branch out, and never go back. I have the corporate plan for $45 and tether my phone to my laptop. I must say the connection speed seems as fast as my wirelsss connection at home. On trips I play POGO games but check my usage regularly because there is a 5gb cap when using the phone as a modem.
