Am a complete newby to this. Have been reading forums for two evenings, and need some clarity Re. tethering. Am going to buy a iphone 3GS 16G soon, and it will have 3.1.3 firmware. Have been told that 3.1.3 can not tether, and have been told it can--confused. It is essential that I be able to tether after jailbreak, so, a few basic questions: 1. Is anyone tethering a laptop with an iphone 3GS, 3.1.3 with MyWi ? 2. Is there some way to tether this phone, other than with MyWi ? 3. Is MyWi stable enough that you can tether for 8 hours straight without going off-line, ie. loosing the connection often, or at all ? 4. Do you tether wirelessly, or with a cable ? 5. Is the transmission speed faster with a USB cable than wirelessly ? 6. If you tether with a USB cable, will the iphone simultaneously get charged while tethering with the same USB cable ? 7. If not, can you tether w/the USB cable, and charge with some other cable at the same time ? Again, thanks for your time and generosity.
