Cydia is an open marketplace for ios
- Also this might break your iphone/ipad or whatever or something like that

1. Go to Settings - General - About look at what version number you have. If you have 8.3 then you are out of luck for a while until they figure out how to jailbreak it. hopefully soon

- the processor is too slow....
For the iPad first generation (A1219) before iOS 5 to update is only possible with connecting the device to iTunes on a computer. Plug it into your computer and open up itunes under devices click on your ipad and then click on check for update.

To use Cydia, you must first jailbreak your iPad.
Make sure that jailbreaking is legal in your country and you must know that you will lose your warranty.

NO
- iOS 6 and higher is not compatible with first gen. iPads!

You cannot install Cydia without jailbreaking an iDevice. Because it is a third-party app store and contains lots of apps and tweak that Apple does not accept.

if you have a first gen. iPad you cannot update to iOS 6:

The only way to get Cydia application is by having your device jailbreak.
If you already have your device jailbreak, and you still do not see the Cydia; which would be due to an error on the device or the IOS version you used.
What you should do is re-jailbreak and from the options just tick on install cydia only.

I do hope this information would be helpfull for you

.exe files are Microsoft Windows Executable files, that can only run on Microsoft Windows. They cannot be run on the iPad, so Safari doesn't download them.
The place to get apps for the iPad is the App Store - have a search, there'll probably be something that can do what you need. Out of interest, what are you trying to do? I may be able to suggest an app.
Hope that helped!
