I am traveling to Asia in a few weeks and I would like to bring my iPhone 3GS with me. However, as you are all aware AT&T is a huge rip-off when it comes to international data packages, $200 for 200mb or something retarded. So I suddenly had an idea, people in my family have world Verizon BlackBerry's (the Tour and the 8830) with Verizon SIM cards. Since Verizon allows you to temporarily go on an international data plan (I believe it's ~$100/month prorated for unlimited data access), couldn't I simply call up Verizon to put my relative's BlackBerry on the international plan and then put the SIM card into my unlocked iPhone? Has anyone out there tried this? If so, any idea whether the billing gets screwed up somehow since the Verizon phone is still being used domestically while its SIM card is being used in another country? FYI I have searched the web for an answer to this and even managed to find posts from others that have the same question, but they unfortunately got misguided answers from retards that say things like "Verizon doesn't use GSM or SIM cards, period!" or "GSM and CDMA are totally different technologies you dummy!". Hopefully there is someone intelligent/knowledgeable out there that can answer this. Just to set the record straight for the aforementioned retards: while it's true that Verizon does not use GSM domestically, the BlackBerry Tour, 8830 World Edition, Storm, Storm 2, and certain aircards all come with SIM cards so that you can roam on GSM networks that have service contracts with Verizon while outside of the U.S. I'm looking at using a Verizon SIM card because it's unlimited international data access unlike AT&T's rape-and-pillage rates; and also this way there is a good chance my relative can continue to use his BlackBerry as usual domestically while I take his SIM card out for a spin internationally.
