Portuguese magazine Bgamer is the latest magazine to preview Grand Theft Auto IV. Most of the information is already known, but there are one or two points worth mentioning:

• You can search "by photo" on the LCPD computer, using photos taken on your mobile phone.
• The other islands are blocked off initially due to a "terror threat".
• The magazine asked R* if there are any Portuguese communities in Liberty City. R* told them to drive to an area in North Alderney, and when they arrived there were various Portuguese flags and posters.
• When a car alarm is triggered, police units in the area will be aware of it.
• R* confirmed that car customization is not possible in GTA IV.

Thanks to uni @ GTAPT for the info.
