Tmobile blocks iphone from using 9.99 data plan.

Hello world. I want to know if anyone else is getting shafted by T mobile. Yesterday 4-24-09 mid day they blocked my $9.99 edge plan on my iphone and now require me to upgrade to $24 a month. WTF. Is there some way to block the signal from iphone to carrier? Like a proxy or some way to pretend i have a pda. All i know is they are sucking more and more. First booted off 5.99 now gettting the boot on 9.99 plan. STOP SUCKING. OOOH i can get unlimited calls for 49.99 ... screw you. crapppp
