I've read terrible reviews of eBay 4.0 for iPhone, and I saw what they did to the pre-universal iPad app a few versions ago, so I refuse to update to 4.0. I have 3.6.1 on my phone currently, but no way to transfer/extract it from the phone for backup. Since Apple has stopped letting us transfer apps from the phone to the Mac, and closed off iOS access to apps like iExplorer, I have no way to get the copy I have off of my phone. I've tried transfer purchases, sync, various file explorers...nothing works. So now I have a permanent update badge on the app store icon on my phone, and I can no longer tap "update all" without getting the new eBay 4.0 app. I had previously found a way to extract just the app from the IPA on the iPad version of eBay, and after installing it via drag and drop in itunes, I am no longer prompted to the latest crappy version. I was hoping to do the same with the iPhone version, but Apple has closed multiple doors on that. So if anyone has 3.6.1 for the iPhone, I can try to extract the app from the IPA like I did with the iPad version, and hopefully install it.
