WiFried: iOS 8 WiFi Issue

1. Alice opens the AirDrop sheet.

2. Alice begins advertising her short "proximity"[2] hashes over BTLE.

3. Bob, continually scanning in the background, sees Alice and her hashes.

4. If Bob either a) has the "Everyone" setting enabled, or b) has a match to one of Alice's proximity hashes in his contacts, Bob connects to Alice over AWDL.

6. Bob starts a HTTP server.

7. Bob advertises a Bonjour service for his HTTP server.

8. Alice sends a discovery request.

9. If the request is valid, Bob sends a discovery response (including device model, name and icon).

Also to note, the author, Mario Ciabarra is the (co?)-founder of Rock Your Phone, the alternative to Cydia until the two merged in 2010[3].

[2] Each device hashes every phone number and email in its address book with SHA256 after normalizing them. These hashes are referred to as full hashes. The "proximity" hashes are the first two bytes of the long hash. The full hashes are not broadcasted, but they are verified later over AWDL.

In any case, after browsing the apple support forums, I decided to try a few of the workarounds there and the only one which worked was by setting my 2.4ghz interface to b/g(legacy)-only mode.

It was an acceptable fix since all my other devices were on the 5ghz and I don't really have any other option(7.1.2 was great for me, shouldn't have upgraded).
