I recently bougth a new Ipad and synced it wiht my iphone and IO noticed most apps look ok but some are a little blurry in full screen mode. I am assuming this is because it was made for a Iphone and the Ipad screen is bigger.
1. In the app store on the Ipad does it only show ipad compatible apps or do you have to sift through iphone and ipad version?
2. I noticed a lot of them said HD, does HD mean it looks better on the Ipad? does HD work on the IPhone too or is it more for the ipad so if I were to upgrade a few apps would it be ipad only or both iphone and ipad?
3. Is there a way to upgrade a app you already have to the HD version or do you have to just re-buy it?
