GTA V – how long does a full set of supplies last

PS3 natively supports bluetooth.

Before you can use the Bluetooth headset with any device, such as the PS3 or a mobile phone, the headset must be paired to the desired device.

You can pair the headset in two ways:

Automatic mode (using the supplied USB cable) - Enables the headset's advanced features for the PS3. Using automatic mode, you can pair the headset with any PS3, but only the most recently paired PS3 will be saved in the headset's list of paired devices.

Bluetooth discovery mode - Sets up the headset as a standard Bluetooth headset. By using Bluetooth discovery mode you can pair the headset with many other Bluetooth devices.

Heists are but one of the many things that can be done on GTA Online. In the future (if) when more heists are added he'll give you a call and give you the details as usual. The basis for this is that the call you receive from Lester letting you know he'll be in touch is the same generic call he gives after every heist.

As far as what there is to do still, I would say that it's a lot like playing real life, there is no "end game" in GTA besides owning a nice place to live and buying stuff you like, so just have fun!
