After installing a new firmware (4.2.1) Skype was deletet from my iPhone. I'm not able to install a new version - Skype requires firmware 4.3 but my iPhone 3G has only firmware 4.2.1
How to get Skype working on my Iphone?????
You could download your previous Skype version if you had iCloud, but that requires iOS 5. If you're on iPhone 3G, you need to always verify app compatability before upgrading.
