i was wondering since i have a g1 but ima get a iphone today if i can use my G1 Data Plan on my iPhone?

You can, but you will be limited to edge speeds

[SoCaL805]

how do i do it? what do i need to do? and what is better t-zone or my g1 plan?

[elsgk2]

T-Zones is worth the cost.
After you've been activated to use t-zones use this apn: epc.tmobile.com
Go to settings>general>network>cellular data network: apn: (above), username and password: leave blank

If you plan to go back to your G1 of course the service will be great because you'll be surfing the internet at far higher speeds.
