Hi I have a developer account from apple does that cover iPad development automatically and the that I can get the beta iOS 4 when apple release it? I'm not much of a developer I just love getting the early software.
Yes, apple normaly puts Major updates into beta for developers. But thats it, just major updates. Hopefully we will see a beta for iPad iOS 4.0 soon. The betas normaly get put up about 2-3 months before that actual release to the public. The normaly update the beta every 2 weeks so you start out with iOS 4.0 beta, then beta2, then beta3.... after 4.0 we probably wont see another beta OS until iOS 5.0 next year.
To make sure your ready for when the beta's are released you will want to log into your developer account, go to the iPhone Provisioning Portal and register each of your devices that you plan to install beta iOS on. if you dont register your device on the developer site before installing the iOS beta it will fail while installing and could cause you a lot of trouble.
In order to register a device like an iPhone or iPad what you need to do is get the UDID for the device, this is a unique idendification ID that is different for each device apple makes. Connect your iPad to your computer and open iTunes. Select the device in iTunes and look at the default summary tab. Click on the section where it shows your devices Serial Number. Normaly people dont know this but it will change from displaying your Serial Number and give you the devices UDID. you can click it a few more times and get things like Cellular Number, IMEI, but those are not needed to register the device in the developer website.
Your allowed to register up to 99 or 100(i forget witch) devices on your account at any one time. I would also advise no to install beta versions of iOS on devices that are not yours for the simple reason that beta versions of iOS expire about 1 week after a new beta version is released. When the beta version of iOS expires and your are still running an old version the device will lock up and give the connect to iTunes logo. It must then be upgraded to the latest beta build. Once you install a beta version of the iOS it cannot be easily downgraded to the latest public version. So once you load the beta OS, that device is pretty much stuck to only the beta OS versions until the final public version is released. This ticked me off with iOS 4.0 for the iPhone 3Gs since either beta 1 or beta 2 completely broke the camera functionality and If I ever tried to use the camera the phone would freeze.
