When backing up my applications from a 2.1 ROM to a different 2.1 ROM, I have no issues. I enjoy using Astro for a File Explorer and recentlly been using it to backup applications. Currently I am using 2.1 again. I've made the switch to 2.2, wasn't happy, and went back to 2.1. Im nowing ready to try 2.2 again but I'd like to restore my applications as apposed to letting the market redownload everything. Can someone suggest an application that will backup my applications on 2.1 and be able to install them on 2.2? I also use Apps2SD hopefully these applications will stay. If not, no biggie, I only have a few apps on my sd. Thanks.
