Post [April fools Prank]I-Spy: Know it All

For the people who want to know EVERYTHING about EVERYONE


3 Months of collarorative work between Madnish30 and myself, we've deceid to make our work public. Early tests made us realise this should be tested more thoroughly with our XDA members, so here we are.

What is it?
Well, let's say you've always wanted to know what kinky pics that hot chick in your biology class has got on her i-Phone. Now you can! With I-Spy, your Android device picks up the radiowaves from other devices nearby (approx. 15 feet) to access the users' device storage, or simply listen into their phonecall!

How does it work?
It's actually very hard to explain, but it comes down to this: I-Spy picks up the radiosignal and decrypts the GSM access codes to get access to the datastream. Then it cloakes itself to blend into the datastream and simply monitor all communication between the devices.

So can I see/hear the complete communication between two people?
No. It's limited to the device in the near vincinity. However, we're working on getting a reversed datastream decryption, so we can get the other device too.

Where can I get it?
It's being developed for Android and Windows Mobile/Phone 7. IOS will be added later. Expect a public beta in the next few days.

Download (Android ONLY)

Download the attached APK.
Do read instructions in post 2 before you run it.

We have only tested it on Gingerbread, so it should work great on that ( and other versions of android too ).

Thanks, man !
Yes, good question. Actually a small tweak in the broadcast of radio signals from devices can sort this issue out, ( Only if network operators knew about this ). They just need to block certain type of decryption.

And yeah, please use it well. Please, don't use it to spy on other people, only for fun purposes !

XDA is about developing and is for developers. Any user that recognizes that will gain the most benefit from this site

This is and always will be a site for developers, pure and simple. Without them we are nothing, without them there would be no reason for XDA Developers to exist; we should never ever forget that. Without them this place would not be called XDA-Developers but something else, e.g Mobile Phone User Support Services For Ungrateful Nerds.

Previous devices: HTC: Treo 650 - Excalibur - Diamond - Diamond 2 - Maple - HD2 - Rhodium - Desire Z - Desire HD - Vivid - Sensation - One V - One X - Titan II - One X+ - DNA - Butterfly

XDA Developers would NEVER stoop so low as to provide an april fools joke. That's preposterous.
