I have the nationwide & the $15 Vpak/vcast for mobile web, i had too change in Dec when , i got my new Voyager phone, no choice, it was the only way i could activate it.
but ON wed i switched phones, i'm testing a xv6900 HTC 'Touch' pocket pc. and i had too switch to the $45 data feature.(still on the NaTIONwide account NO way to go back to AMC after 5 months) to make full use of the mobile internet & data services, if ( at the end of 30 days ) I go back to the voyager and the $15 service , depends on how well i like this phone and IF i can get the NEW $30 PDA data plan that came out on the 14th but is only available for (3) phones and this one isn't on that list of (3) , that feature-plan is supposed to be rolled out to more WM-OS smart devices soon. ( depending on what vzw means as soon )
