Okay,we are having a misunderstanding here,You could blame me for not making things clear. First of all money is not the main issue here,10$ isn't much but the way to use it is the issue. Why did I say I am not willing to buy any app now?
Reasons:
1.I don't live in US
2.AppStore doesn't support my country.
3.I don't have a credit card.
4.Paypal doesn't support my country
5.People I know that used to live in US often charge me 2x the real price of anything,for example,when I asked a friend of mine whose uncle was finally retiring from US to get an iPad for me,I had to pay 1341USD+other extra fees I really don't understand the purpose of,to get me an iPad 3G 32GB. But now that my friend's uncle is back from US and won't be returning, I don't know anyone else who can do the buying for me.
That's why I said it's pretty expensive and impossible for me to afford any paid app.
I think I made myself quite clear. Now we can go back to the real suggestions and discussions.
Thanks
