Hi PaulS, i should have explained better. I want to connect my iphone 4 through bluetooth to my arduino UNO and then check if the device is on the database list, which will then connect to a server through WIFI. The server will then allow the signal to be accepted and open my door. I have found out that connecting to the iphone IOS is only done now through a bluetooth BLE (4.0) without enrolling in apple's MFI program and people are still working on it, i have yet to find any sellers.
