I'm going to pretend that I sort of understood all that... lol (I think I did)...
But is that speed really necessary. I don't play games and am not really much a player (other than boring word games lol) so I don't really think that aspect of needing the 4G to be applicable to me. I think for me it will be a lot of internet/facebook/twitter usage and texting (which I think I can do via GVoice and not have to pay for a texting package).
For that type of use - do I need the HSPA+ speeds? Or is Gingerbread more important? I think those are the two things I need to decide between but have yet to really find anyone to give me a clear idea of what I will prefer.
What do I want/need more: 4G or 2.3?
Am I right? Are those the basic differences between the phones (other than NS being vanilla)?
