   I think it's OK to connect to VB_SYS.

If we use USB supports the VB_SYS, we can't plug any USB device. Because 
we use the same USB port.
Therefore, we don't need to change.

Like tony's suggestion, phone always uses the battery to support the power.
Adaptor or USB is not good for supporting  the GSM power.
