If remember it works like this exactly
i'm telling for iphone 3gs 8gb which is 99$
You pay 99$ and onemonth advance of 75$,and one time activation fee like 36$ + Early termination Fee(ETF) 200$
all fees vary +/- 5-10$. , i havent cross checked,just posting what i remember
so it comes 99+200+75$+36$ = 410$
I have seen in some forums,but it really dents someones credit records if it happens frequently and
so u can get it for well under 20 k a new one.. it becomes officially unlocked too
Not all relatives and friends do this for you..!!
