Hardcoredan52 did provide accurate information for instructions on tethering and MMS. (Thank you!) I just tried the tethering trick (after an hour's worth of work!) and I can tether my MacBook Air through USB. For some reason, Bluetooth doesn't work. Whenever I try to establish a connection with Bluetooth, my MacBook Air says,
"Failed to open a connection to the network service. Your device may have reached its maximum number of supported network connections."
I can't figure out why either. I should be thankful that at least Bluetooth works.
I have not tried MMS yet, for I am a scardy cat that I will be "charged" more for MMS messaging when sending and receiving them. (I already hand in enough money to AT&T!) I already have the unlimited texting plan for my iPhone (not the unlimited family plan texting). The reason why I held back on this one because of the ***USE AT YOUR OWN RISK*** warning. Is it safe to continue with this little trick to get MMS? 😱
