My iphone 3gs can only get an apple symbol. It recycles on & off only, never getting to a red slider. On a different computer, itunes tells me my passcode is blocking me. Ingenious!!! I'm painstakingly backing up my data manually, as I thought I had backe

I wish I could adequately describe my frustration with apple. Anyway, my iphone 3gs gets nothing but an apple symbol, never getting to a red slider. On a different computer, it tells me I must overcome the passcode, Ingenious!!! I'm painstakingly extracting photos from it a few at a time. I thought it was backed up before but it wasn't so. My phone cycles off and on every few minutes making backup and restore impossible or so I thought. Though it didn't restore, it does say there's a backup. I'd like to know if it's a full backup of all the data on my phone and how do I determine that? I tried to change a contacts file to a file that could be used outside of Itunes (csv) but no luck. I feel like I'm in the twilight zone. I'm sure my iphone is not repairable as I've tried it all. Sigh
