Hi, My gf has the old 3G IPhone...I recently upgraded her to OS 4, but it was so painfully slow that I downgraded back to 3.3.1. She didn't lose any important data (contacts/photos/etc.) but all her apps went away...and now she can't re-download some of them (mainly Facebook) because the OS is too old. Does anyone know of a way to search the App Store for older apps that still work on 3.3.1? Or know the name of a FB app that would still work? She's not a really heavy user, using it mainly for navigation/texting/FB, and not very technically inclined, so would prefer to find an app that still works than jailbreak. Thanks in advance.
