I haven't seen this addressed anywhere else, so I'm asking it here: I'm running MediCkOne's FRG22D ROM, and am having issues related to Launcher Pro and apps that won't download/install. Sometimes when I can clear cache for an app or the market, it clears; but when things all show up in Manage Applications as "Computing...", forget it. Nothing I set there changes anything until either I reboot or the phone digests whatever it's trying to do.
My question is, what happens if I go into SPRecovery and just wipe Cache, and nothing else? Will everything else stay intact, as in apps that are installed, etc., so I don't have to flash the ROM or run a full Restore, as wiping Data would have me doing?
