I have accident update the skype for iPhone, on iTune, to the latest version (3.5.117) and I also restore the firmware of my iphone. I do not have any backup for the skype. The latest version of Skype does not support my iphone 2G so I could not install it in my iPhone. FYI, before I flash firmware, I have used skype without any problem. Anyone has any idea to get the old version of the skype.
I found the way! If you still have the older version in your recylce bin, you can delete the new version from your phone, then in Itunes, then sync it. Then click on the old version, it is a file ending with .ipa - it would autimatically appear in your apps in Itunes, and then you just sync your phone. If you dont have the old version in the trash, let me know, I can email it
