maximum trigger depth error

I have a trigger on task that will update the task with the accounts record type on insertion.
I also need to do this on an update, but get the "maximum Trigger Depth" error when adding before update to the trigger.

trigger TaskAccountType on Task (after insert) {
    Task T = [select Id,WhatId,subject from task where Id = :trigger.new[0].Id];
    if(trigger.new[0].Id!=null){
    string WhatId = t.WhatId;
    
    if(t.WhatId!=NULL){
   if(WhatId.startswith('0')){
    Account a = [select id,recordtypeid from Account where id =: trigger.new[0].AccountId];
if(trigger.new[0].AccountId!=null){  
if(a.recordtypeid == '012i0000000Ou0CAAS'){
        t.Account_record_Type__c ='Customer Account'; 
        update T;       
        }
        else
        if(a.recordtypeid == '012i0000000Ou0EAAS'){
        t.Account_record_Type__c = 'Prospect Account';  
        update T;      
        }
        else
        if(a.recordtypeid == '012i0000000Ou0DAAS'){
        t.Account_record_Type__c = 'Partner Account';  
        update T;      
        }
}
}
}
}
}

This is due to the "infinite" loop you set up!!  Inside your Task trigger, you update the Trigger, causing the trigger to fire again, and again, and again ...

OK, I have made the following code changes. Works fine on update, but not on insert. Record Type is not stamped on the activity.


trigger TaskAccountTypeContact on Task (before insert, before update) {
   For (Task T : trigger.new){            
            string WhoID = t.WhoID;
    if(t.WhoId!=NULL){
   if(WhoID.startswith('0')){
   if(T.AccountID!=NULL){
    Account a = [select id,recordtypeid from Account where id =:T.AccountId]; 
if(a.recordtypeid == '012i0000000Ou0CAAS'){
        t.Account_record_Type__c ='Customer Account';                
        }
        else
        if(a.recordtypeid == '012i0000000Ou0EAAS'){
        t.Account_record_Type__c = 'Prospect Account';                
        }
        else
        if(a.recordtypeid == '012i0000000Ou0DAAS'){
        t.Account_record_Type__c = 'Partner Account';               
        }
}
}
}
}
