can someone make this very brief .... iphone 5

i had a iphone 4 so i m fully aware of the phone.

what exactly are the differences added to the iphone 5

i dont understand the tech terms too much but i have gathered that

iphone 5 is thinner
iphone 5 is taller
iphone 5 uses LTE (i dont know what lte is and how its better than whatever was used before)

if someone can help me understand other differences it would be much appreciated. in simple layman terms

for what's different between iOS5 and iOS6

LTE is the ability to get internet speeds as fast as most home networks. up to 100mb/s.

iPhone 5 also has a better camera, 3x as fast as the iPhone 4 and 2x as the iPhone 4s and you get a brighter screen (retina display).

I would suggest taking the time to watch this video and it should answer all your questions.
