I would like to have downloaded ios6 so that I can download gumtree it won't let me download it otherwise plz

hi see here

Gumtree for iPad on the AppStore

Unfortunately you can only update to 5.1.1 for the ipad1

If you're still on iOS6, you should open 'Settings', 'General' and go to 'Software Update'.
You may also connect the iPad to your computer, open iTunes and Check for Update. iTunes will download and update for you.
If you're on iOS7 and want to downgrade, that's a problem. You need to google this as it is complicated, and probably not possible.

To be able to install Viber, your iPad needs at least iOS 6.0 Apple did not release iOS6 for the iPad 1. So your is running on iOS 4 or 5.

Yes if you have an apple tablet

if your ipad is on iOS 7 and above there is no way to go back down to ios6.

Plug your iPad 2 into the device where you run iTunes. In iTunes, select the iPad in the left column, then select the Summary panel. At the upper right, continue by downloading and installing the latest version of iOS that will run on that device. We use iOS 7 on our iPad 2 - and it runs very nicely.

For the iPad first generation (A1219) to update is only possible with connecting the device to iTunes on a computer.
- this model supports only iOS 5 - NO iOS 6/7/8
