Alright, so I'd been having issues with my phone for a while and finally gave up and called Verizon. They overnighted me a replacement and thus far it's working much better in every way except one. I have the old style Android Market installed and I cannot get it to update to the newer version. I went to XDA and downloaded the stock 2.2.6 APK but when I try installing it through Astro it says "could not open as APK file." Any ideas? I installed the Amazon Marketplace app from a downloaded APK so it's not something simple like it just can't handle non-marketplace APKs.
