is the IDA is comes from this source? (http://apt.ripdev.com)

bro, i couldn't find the malaysia map for ida leh...

Guys,i find out the way to use malaysia map in ida,but i need to pm moderator first to double confirm wether is legal to show the step here or not...anyway, i prefer to use xgps than ida coz it cannot key in the exactly home address or load the contact's address like xgps....

I got it ^^. Thanks.... Now wait for tomtom and c how interactive on this .... Hopefully it provide the same features like xgps,can load from contact's address...anyway the new xgps 2.0 will launch in app store and is worth to buy it ^^

1. Please note tat iphone is only come with a-gps,so it may need to use a little bit usage on 3g.
2. Pretty accurate..
3. No idea
4. Just buy the car charges which is cost about rm40
5. Yes! its support multilanguage such as cantonese, mandrain and malay as well

no, AGPS may required the network in order get more accurate location on the maps. and its require network to route the destination as well.
