Newbie, do I understand the iphone4 correctly. I'm thinking of upgrading from my Cingular (now ATT) Razr to the new iphone4. My most important reason for jail breaking is tethering--it is essential that I be able to tether. My task: I have (1) an ancient Cingular Razr (now ATT) that I have been using for years; (2) a 3G aircard/Globetrotter (ATT) that I have had for about 8 months; (3) an ancient Palm Pilot Tungsten calendar (non-phone) that I have been using for years; (4) a wand document scanning device; and was thinking of buying (5) a Tom Tom GPS device. I am looking to upgrade and replace all of these FIVE instruments with a new iphone4 that I intend to buy as soon as I can. So I need some very basic clarity from the knowledgeable contributors on this forum Are these statements correct-- yes/no ? Nomenclature: 1. The new Apple/ATT iphone model is called the iphone4 ? 2. It will come with the new operating system called iOS4 ? 3. There is a new wifi system by Sprint called 4G ? 4. The nomenclature of the iphone4 does NOT mean that it is a 4G wifi system ? Jailbreaking: 5. There is not yet a jailbreak for the iphone4 / iOS4 ? 6. ATT does not offer tethering in any of its plans for the iphone4 ? 7. To tether this phone, one needs to jailbreak it ? 8. I need to wait a while for a jail break hack to come out before I buy the iphone4 ? Any additional info you can offer would be much appreciated. Thanks for your patience.
