Alltel service with no data plan

[oneajk]

I Have a Verision 6900 that I unlocked and set up a with custom ppckitchen ROM on an Alltel network. I have no data plan through Alltel, and was wondering if I could set up the vogue to use airtime minutes instead of a data plan for minor weather, and internet browsing?

If not, can I set up internet sharing through my laptop, so that my phone can access the internet when connected through actisync, usb, or bluetooth?
