I'm going on vacation tomorrow and need mobile data access for 7 days. Have been considering various options including EVDO, Sierra 3G cards, and of course the iPhone. For the iPhone what is the better tethering solution? The latest tethering hack or a Jailbroken phone using something like PDANet? Also I need the access on a Windows Netbook, not a mac. I also have the regular 3G iPhone with 3.0 firmware. Cheers.
