Can I use the iTalk Sync Application if my computer's not near a wireless network? (PC)
Even if you're not near a network, as long as your computer is wifi ready, you can set up an "ad hoc" computer-to-computer network to transfer those recordings. First, follow the appropriate instructions for setting up an ad hoc network in XP, Vista, or Windows 7.
Now, on your iPhone, choose Settings, then WiFi, and choose the new network you've created.
Finally, get the iTalk App running on your phone, then run the iTalk Sync app on your computer and you should be in business.
