I bought an iPad in December and love it! I've become an Apple convert and yesterday my iPhone 4 arrived. We have Verizon as a carrier and I went with the 2 GB/month plan. I'm completely new to smartphones and data plans so I have lots of questions. What tips do you have to keep my cellular data use at a minimum? I have wifi at home and at work, which are the two places I'm at most of the time, so that's a good thing. I don't want to go over the limit but yet I also want to take advantage of the data we are paying for. I'd also love to hear about what apps you have on your iPhone that you just can't live without. Since I have an iPad also, I'm thinking that most of my game playing & so on will be done on the iPad. I would like I'll probably use the iPhone for more "productive" or "useful" type apps. Any ideas or tips? Thanks!
