the Maps app gets its map tiles from maps.google.com, so you need to be online (3G, EDGE or GPRS for it to work correctly.

document editing is not built-in to iPhone OS, please search in App Store for it.

so far, I've only seen good results with AmBank NexG prepaid.
only thing is, they told me 2 weeks to activate the card.

Get the card from your nearest 7-eleven, then go to nearest AmBank to activate it. need to bring your MyKAD for that.

my buddy is using this... i've registered and waiting for activation now.

the malas part is, need to reload cash into the card, using AmBank CDM. other than that, its all fine.
