I an running a rooted Droid X with the 340 OS on it. I am planning on using the maderstock file to revert to stock 340 anticipating that I will upgrade it to GB. I have a few questions about the upgrade that I would like to understand before doing the upgrade. 1. I have a number of paid apps on the phone now. If I do the upgrade will the market app know which apps are paid previously or will it lose that info? Do I need to save these before I do the upgrade or just reinstall from the market? 2. For free apps will the market app remember them or will I need to do a fresh install? Should I save these as well? 3. Is it possible to install maderstock without doing the factory reset? It seems to (sometimes) cause boot loops but I don't know if this always happens. 4. If I delete the cache and reset it, do I lose any info saved by apps such as serial numbers or is that info saved elsewhere? Thanks in advance for the help.
