How much does iPhone 5 cost without free upgrade?

I currently don't know when my next free upgrade is. I'm with Verizon. I want to upgrade to an iPhone 5. I heard the iPhone 5 is $199 with a free upgrade. How much does Verizon charge to get an early upgrade? And how much will that cost all together with the phone, cost of upgrade, and taxes.

Should I preorder the iphone 5?

I can't decide… I was going to wait for it to actually come out, where reviews would already be out because I don't know if I want the iPhone 5 or samsung galaxy s3.
My brother has the samsung galaxy s3 & I don't really like how big it is, in general I don't like the phone.
But my friend has the iphone 4 and she charges it 2x a day which is ridiculous.

What's the difference between GSM and 3G?

I want to get an iPhone and use Petro-Canada's mobile service, which uses Rogers' network (http://mobility.petro-canada.ca/en/features/396.aspx) it is a prepaid service, and i'm using because its cheap, but i guess no data for me (all data plans are expensive, and Petro Canada mobility only offers "Unlimited Mobile Browsing", which is really only for websites and such, not apps - it differs from Data)
Anyway, they say that in order to use my own unlocked phone with their mobile service, it has to be GSM compatible, and the iphone is (iPhone 4S).
Anyway, i did a little research about what GSM is, but i couldnt really understand, some say its a Data and Cellular service, and and some say its only a cellular service (only for calls and SMS, not related to data and mobile internet).
So now i'm confused, what is GSM?
is it data and cellular-related or just cellular-related?
Same questions go with 3G, is it a data-related thing? Or data AND cellular related?

Can you have 3G internet/data service with a GSM mobile network?

also, what is the difference between 4G and LTE (shouldnt they be the same)? And what's the difference between 4G HSPA+ and just 4G or LTE?

thanks a lot, all help is greatly appreciated!

Added (1). So are EDGE and GPRS data or cellular networks?
