ok im posting this for those who might encounter the same problem i have coz integrating paypal can really cause you sleepless nights (Atleast for me).
There are a lot of posts on integrating paypal to ci esp using their ipn.. well actually almost all of the codes are fine, here are the things you have to check that might be the cause of unusual results.
* When testing in sandbox, the receiver's email is different from the email used in creating the sandbox account.
* make sure to set the IPN notify url under your profile inside your account or make sure to set a notify_url in your form
* When pending result is returned, make sure receiver and the sender test accounts are verified.
* Always check your logs to monitor whats happening
* Im not sure about this one but sending data from session under the IPN method doesnt arrived. I just concat all the data to be passed inside the custom field. (ex. customer_id=1|order_detail=5|etc...) then do an explode together with a loop to fetch all the passed data.
* When sandbox isn't responsive or always generating an error, KEEP RETRYING! ;-P
