I tried the Reading list app, i visit a page on the internet and share it to reading list. and then i turned off my wifi and data, and access my reading list. i was very glad i can still read it the whole page, until this morning when i check it again, it was not working anymore hehehe maybe it will work offline right after you saved it but after few minutes it wont allow you anymore...i also dont have a credit card but my sister does, maybe i really need to have one of my own so i can use it in buying apps.
