I tried to download OS4. My computer and iphone froze halfway through. I rebooted my iphone and had to reset to factory settings. When I try this I get error messages (21, 1300). Please help. How can I check my security is off? Have tried Apple's trouble shooting suggestions. No luck.

MacBook, Mac OS X (10.4.11), iPhone 3GS
