Yes,DiGi is unlimited, the fullspeed (if u can get it) till 1GB limit, then it slows down to GPRS....but data still free after that....

Added on May 8, 2010, 2:09 pmJust for those who were asking, iPhones are set to access data ALL the time.... examples:-

Mail.... once open, it does not close... its always running in the background, even u exit the app..... and if yr setting is default, it will always check for new mails....

Apps: Most FREE or LITE apps has ads.... these ads are dl-ed off the air via yr data...

Notifications: most push notifications apps (mails, IMs, Facebook, Tweets, RSS) all are data sent to you...

Location services: Some apps asks to use yr location, but not all uses the GPS chip, instead they get yr location data via the phone broadcast stations (aka A-GPS)... these are data...

GPS: Apps like Maps, Google Maps and GPS starts with A-GPS, which triangulate yr location using phone broadcast station... and then dl maps from Google... all are data...

Auto Lock: When iPhone goes into auto-lock, the WIFI is set OFF.... so if yr apps or mail or browser is dl-ing when the iPhone auto-locks, it uses 3G or EDGE or GPRS to continue dl-ing.... and thats data...

So, by the list above.... even if you dont SURF using Safari or Opera, u will still leak data...

Oh.... and u cant disable EDGE or GPRS from the Phone.... unless u..... do something i cant mention here....

Maxis and DiGi will not be so dumb to completely disable yr data plan as they know this is where they make money.... u think they subsidize almost RM1000 off smartphones just because they are doing YOU a service, or they have too much money and they wanna share it with you.... LOLZ...

Thats the cost of owning a smart-data usage-phone... get it if u know what you are getting into, and have a data plan ready....
