If you are like my wife and I, with a family plan that is about 2 years old, then you should be able to add "unlimited internet" for $10 a month to each phone. If you just want "some" web access, you can use the t-zones (5.99 a month or even free) and use the blazer proxy setting of:
t-zones (web proxy 216.155.165.50:8080)
You can't get streaming media, or other protocols, like ftp or https with t-zones, or use any application that does not have a proxy setting, but you can browse "normal" http: sites to your hearts content.
One of the "tricks" is to log into my t-mobile and select your phone. You get different options based on what phone you select!
