This afternoon's Cover It Live liveblog with TUAW readers provided us with some great info about the iPad Wi-Fi + 3G, which is available from Apple today! Here are some interesting notes provided by readers, our own bloggers Erica Sadun and Steve Sande, and special guests (and iPhone/iPad developers) Nate True and Kyle Kincade:
• Reggie Suplido tried calling his iPad. Every iPad that's signed up for digital service is assigned a phone number -- and he was curious to discover how it worked when called. He reports, after trying this, that it said "The person you are trying to reach is not accepting calls at this time..." He also tried sending an SMS message. The iPad didn't receive it.
• Several readers tried using Skype over 3G connections and, as expected, failed.
• 3rd-Party International SIM cards were confirmed to work by our readers. One chat participant experimented with an O2 Germany SIM and reported success.
• Unfortunately, the 3G iPad signup process experienced difficulties. One reader reported, "I just signed up and after a lot of headache, the credit card went through. I then got a timeout." After, he was not able to "Add Data" to his account. All we can say is be patient - a lot of people are in the process of activating their iPads right now, so you may run into this issue.
