Hi, I'm considering getting a 3G iPad, but I have a few questions: - Can I send/receive SMS messages on it? - Can I make/receive voice calls on it? Also, I know that iPad currently has no multi-tasking, but can I run a download manager app, set it to download from my 3G internet connection, and then put it to standby and just keep it in my bag while it downloads stuff? Or does that count as multi-tasking? What about if iOS4 comes to the iPad, will this be possible? Or are no apps allowed to run in the background when in standby? Thanks.
