if so okay, but still i do confuse with the limitation of 100mb.Sometimes facebook apps can update more then 100 mb and some apps cannot update over 100 mb.
I didn't downvote you, but I can help you understand why you were downvoted.
On HN, you'll usually get an answer if you ask a question.
"Is x going to be a problem for y?"
Making an incorrect statement however will get you downvoted.
"x will be a problem for y."
The other issue is your writing quality. You will get better results if you put more effort into your writing.
You don't have to have perfect English. Many people on HN have English as a second language.
Things like a capital letters at the start of a sentence, and using single full stops (periods) at the end of sentences, show effort. You will find people will be more tolerant of grammar issues if you at least put effort into the basics.
