Question

I can't find away to upgrade my frist gen iPad that has the 5.1.1 iOS just wondering if anyone

Answer 1

Nope.
iOS 5.1.1 is the last and maximum iOS version the original 2010 iPad can go.
Once April 2015 hits, the original iPad will be 5 years old and still won't ever receive any new upgrades or updates.
It's time to start looking at new or "newer" ( used ) iPads.
If you decide to pursue the used market for iDevices, forget eBay and look to Apple authorised resellers that sell both used and new Apple products OR look at the refurbished store section of Apple's main website for specials on iPads.
FYI, if you want and iPad that'll be, somewhat, future proof, do not look at anything older than an iPad 4. iPad 2s, currently, are NOT up to the challenge of running iOS 8 or any future IOS versions as far as I am concerned.
And as a iPad 3 owner, while my iPad 3 is running the latest version of iOS 8, it's not running it nearly as fast as older iOS versions and I feel it won't be able to handle or be eligible for a future IOS 9, whenever that will be coming.
So stay away from iPad 3s, as well.
