Currently on Verizon, but really want to get an iPhone 4. My basic needs are: lots of texting (500-1000/month), very minimal voice/minutes (100-200 minutes), and I would probably skip a data plan since I have wireless access 80-90% during the day, and as long as I can get texts/calls, data isn't needed every single second of the day. What's the easiest way to get a cheap/convenient SIM card for this to work? I don't know much about how GSM works, so this is all pretty new to me. Is getting a GoPhone and putting the SIM in the IP4 my best bet? Any advice/expertise is much appreciated!
