If your phone isnt a cid 53 and is a cid 52 or lower it is NEVER A GOOD IDEA to upgrade/reflash to cid 53 because half the modding programs are still not compatible with cid 53 phones,i know this cos i accidently upgraded one of my phones to cid 53 and i cant do half as much stuff as i can with a cid 52 or lower, i CERTAINLY cant patch it. Sony Ericsson relesed cid 53 to try and stop people modding their phones!!!
