i noticed that about the 2g, but most phones would be compatible with that right?
You would just need a 3G handset to use this hub. An old handset (but also many cheaper new handsets) would probably not work. It depends on your definition of "most phones" but I think the majority of phones in circulation in the UK are still only 2G. However there are plenty of new phones, such as all smart phones as well as all on the "Three" network which are 3G compatible. You can see whether your phone is 3G compatible or not by searching for its spec on a site like
http://www.gsmarena.com/i guess what that means is you can call and text, but not surf the net? is that right?
No. The 3G only refers to the mode of communication between handset and hub. AFIK there should be no reason whatsoever that the hub is not fully data enabled as normal on 3G communications. So phoning, texting, surfing, picture msging and video calling should all work on your 3G handset as normal!
