I've been reading about people who keep attempting to downgrade, jailbreak, restore, etc... and do this multiple times because it doesn't always work successfully. Is it harmful to the phone, hardware/software-wise, to keep restoring, putting it in recovery or DFU mode, multiple times? When I had my 3G, I restored quite often when jailbroken apps caused issues, and I never really thought about the long term issues that may arise. Now that I have a 3GS and awaiting the Dev Team's JB, I'm curious to know of any damaging effects. Please shed some light. Thanks.
