Okay this topic has probably been posted on here several times, but for some reason i just can't seem to find any of the threads.
I just bought a really cheap Bold and i have the iphone 3G right now.
I want to use them interchangeably, but Im not sure what plan i need to be on.
I know about how they may find out about me using my iphone and switch my plans, but i won't be using it for more than a day a week if at that. I just want to still have the flexibility.
