I have a BLES save that you can use to unlock Liberty City (5). I'll upload it to the xploder database (I'm not into using file share sites, sorry). All you have to do is call up Packie at the right time and take him out once to increase his like above 90% and then the trophy will pop. This isn't my save but one I found on this site a while back, so all credit goes to the original owner.

Anyone know of any good saves that can be used to unlock the following:
Courier Service - 10 package delivery jobs
Order Fulfilled - 10 Exotic Export orders
Manhunt - all most wanted side missions
Under The Radar - fly under all the main bridges
"How We Roll!" & "Dial B for Bomb" are both friend related and require you to get Brucie and Packie above 75% likeness

I think all the saves would need to be from right before the requirement is met, cause most can only be done once.

ive got key to the city, pigeons, stunts, just wondering if there are any more saves out the ?

if so please upload or link me
