Paid survey apps for iPhone?

Does anyone know of any good paid iPhone survey apps or even just websites… Preferably Paypal paid ~ but you have to answer alot of survey's to get like $10

I did a separate survey last Tuesday, it paid me $75 for about an hour and 10 mins… I am waiting for the check to come in the mail

If you really want, email me and i will email you back if the check arrives, then the site is a good one.
