Is this easy to do. I'm about to switch over to Verizon after selling my ATT Iphone 4. I plan to pick up the Verizon Iphone 4. I'm switching due to coverage issues up in Vermont where I spend a lot of time. The areas I frequent have great Verizon service but no ATT service. Now that I will be on Verizon, I may also pick up an android device. I know it is not as easy as switching sim cards on a GSM phone. Are there any people who have been switching back and forth between the iphone and an android device? How do you accomplish this on Verizon? Thanks for any feedback.
