Thank you.

btw im paying fg for a solution to this ^

looks like you still don't understand the difference between the word unlock and jailbreak..........

i do, but it clearly ain't the same thing

u obviously don't considering the question you want answered..

maybe someone has more knowledge on this subject than some vietnamese ppl who can't b bothered trying to help some foreigners

if u can read between the lines

im going to explain it quite easy for you.. when you buy a phone (legally) the phone is locked to a operating company (normally when you buy iphone or other phones which you pay x amount each month) or you can buy a phone unlocked aka it can be used by any operating companies (this is normally for those phones where you pay full amount when you buy it and not the x amount each month. some phones (like iphone) is not possible to get unlocked in the western world (not 100% sure about this, but iirc its right)). if you want to bypass the locking you can jailbreak the phone (which is what you have to do, if you buy the phone in vietcong). when jailbreak is completed any operating companies can be used.

hope this explains what you're searching for.

thx for trying to explain norm

the iphone 4 was purchased legally in the USA but is locked to the american provider none-the-less, and unable to be unlocked in vietnam as we have been told.

the way i interpret jail breaking as it has been explained to me, is that the App store will not be accessible and hence all or any program updates will not be available instantly, which is not acceptable to me and therefore pointless.

having to frequently manually check for updates for every single program/app as opposed to being automatically informed of all latest updates through the App feature makes jail breaking not an option if this is the case.

no problem. not sure about the program update part though (never had any jailbreaked phones), but what you write about the software upg for the phone itself is correct though.
