you cant. you need to go to an apple store.
Sure, jailbreak it. Probably not a good idea unless its your iphone.. because stealing.
Personally, I prefer the Iphone 4s-but that may be beacuse im biased since I've only known the Iphone, but put it this way, the Iphone 4s is much more popular
You have to put a small tacking chip in the sim card and download an app on your 4s to track it
That requires jailbreaking to put widgets on your iPhone. Currently there is a tethered jailbreak for iPhone 4S But it i highly recommended that you don't jailbreak.
The iPhone 4s is the 5th iPhone that Apple has made.
iphone 4s
No. iPhone 5 is not better than the iPhone 4S.

iPhone 4s is easier to use, but it depends on which Htc, I would say the iPhone 4s
It depends. If the iPhone 4 case is for the GSM model (AT&T) then you can put it on, but the ringer slide button will be partially obscured. If the case is for CDMA models (Verizon) then yes, it will fit because when Apple made the Verizon iPhone 4 they upgraded it to be slightly different, and that is the shape all iPhone 4S's are now. iPhone 4 are very similar in shape with iPhone 4S. If you really want, you can put the iPhone 4S phone into a iPhone 4S case. but it may seems no good in apperance, as they are not exactly same.
The iPhone 4S was invented in California by Apple
not a 4s but he has a red iphone 4
