Wanting to Get My First iPhone

Question

Hey-
How can I get an idea what size iPhone 4S I should get?  Is there a way to get an idea not only on the processor size but also the plan type.  Right off I want the biggest to accomodate all the HD videos I take for work, but I really have no idea what size and pla I will need?
I have a Mobile Hotspot 3G now but I was going to get the MIFI 4G.  Does tethering do the same thing as a Mobile Hotspot does like the Verizon MIFI 4510 4G?  With the new iPhone 4S can you use your MacBook Pro wirelessly by setting up the iPhone a certain way (which I assume is what is called tethering)
this might get this question knocked of of this discusion, but does the iPhone 4S work best on the ATT network since they both came at the same time and that is the network the iPhone grew-up with. 
If the smartphones with the dual core processor are coming out, would you wait for this phone before getting an iPhone 4S (it looks like it has some new functions like Siri and it does have a dual core chip)
thanks for the help.

deggie-
it seems like you know a lot o what I want to now more of.  Is it possible to PM you to clarify some of what you stated?  It confusedme more. I am not aware that my cell phone has a bowser.  Does it have a browser because you can connect to the internet, is that what you mean by the browser?
What I realy need to state, the moderators will remove my post if I ask what I realy want to know because I am with Verizon, and my questions are about staying with them because my contracts for the cell phone and the MIFI (their mobile hotspot, but mine stopped working and it is 3G.)
I was told that Verizon, actually i have been told so much I am so confused if I should say with Verizon or go to ATT and tap into this ad I see for the Apple Store where they charge you full price but throw in some classes, pay for applecare (which I could get at Verizon) but I have never even used a smartphone or iPhone so the classes they talk about in thier ad appeal to me.  I am not talking about one-on-one but I gues they get it all set up for you before you leave.
However the Apple Store will not give me the New Every Two that Verizon used to have but is still giving it to customers who have not used theirs yet.  which I do, so if I go to ATT I would lose the New Every Two, rebate type money that they use as staying with Verizon.
I would not want to be using the iPhone as a hot spot and then get an important call. what do you do if that happens?  that is why I like the MIFI 4G and ATT has one like it, you take it with you, can put it on your dash on a road trip and use your mac or any laptop.  But if the iPhone can do the exact same thing I am not sure I need to pay another $50/mnth for the MIFI 4G.  If it does cost extra to add tethering to your iPhone then how do they know how many people are using it, do they go by how much GB you use per month?
A friend and I looked at her HTC Android phone under WiFi andit had her password and some other tuff which she did not know and it also said 4G, which was confusing because her provider is TMobile, but where she lives her reception is really bad, which is what I am dealing with now with my MIFI 3G so I am not sure of the 4G MIFI will work in the area I live.  On Verizon's map it says yes I will get G but there is a small area that everybody has a problem with their 4G reception so the maps are not always able to give the whole story.
I spend so much time, years it has been and I am still using this 7 year old flip MOTO phone.  I just need to do it.  Like you say the next iPhone will be 4G, but if I keep waiting I will be waiting until I am dead before I et a iPhone or smartphone.  So I am going to sign up for that service the Apple Store advertises, they will set your phone up, do some teachng, get you connecte to your new provider and plan, and then when that is all done I can cancel the plans I have now with Verizon.  Personally I think if I get an iPhone I should go to ATT.
