Help required please. "Itunes can not read the contents of my iphone"

Question

Greetings all,
I know this question has been asked before and I apologize for asking again but all the solutions provided don't seam to work for me, can anyone help me please.
I am receving the message: "Itunes can not read the contents of the iPhone. Go to the summary tab In iPhone Preferences and click restore torestore this Iphone to factory settings".
Now a little about my iphone, Itunes and my laptop and what steps i havealready tried.
I have an iPhone 4 running software 5.0
My itunes version is 10.5.0.142
I know these are not the most up to date versions but I have had this issue for almost 3 months now and updating the software back then was the first step I tried. I don’t believe updating to the latest will fix this issue as updating the last two times did nothing.
Every so often after starting Itunes, The program will stop responding and will require the three finger death kill (CTRL, ALT, DELETE) to open task manager to end the task of Itunes. Once it shuts down, I restart the iTunes and it runs smoothly, apart from not reading my iPhone.
When I run a diagnostic in itunes under the help tab, I get these fail messages:
Network Connectivity test: Secure link to Itunes store fail
Device connectivity test: Under support services: Itunes helper is not running. And under ports: No iPod, iPhone or iPad found.
Device Sync test: No iPod touch, iPhone or iPad found.
*See below for full diagnostic report*
I have restored back to factory settings twice.
I have shut down and restarted both my iPhone and laptop.
I am running Windows 7 32-bit on my laptop.
I am using ZoneAlarm as my fire wall, and have been disabling it when syncing my iPhone to prevent other error messages.
The iPhone is plugged into a genuine Iphone USB cable and is plugged into a USB port not a USB hub on my laptop, I have tried plugging it into all 4 USB ports and this issue still persist. The Cable is less then 5 months old, is not frayed or damaged in any way, have also borrowed 2 other cables from friends and still the same issue.
The iPhone does not even come up in windows explorer as a digital camera.
The iPhone is NOT jailbroken
I do not live close to a so called genius bar, however I have made the journey to them on 3 separate occasions last year when I first received my iPhone for a different issue, the so called genius's could not fix the problem so they just gave me a new (refurbished) iPhone, which did not extend my warranty. I will not be taking the iPhone back to them as I believe they can not resolve many issues, this is why I am reaching out to the power of the people in the wider apple community.
I have read in other forums about ifunbox and other programs for jail broken iPhones to isolate folders “iTunesDB” and "iTunesCDB" and delete them. If this is the issue is there a way to access these files through windows explorer as my iphone is not jailbroken.
I hope I have provided enough information and someone can help me fix this issue. If I have left anything out, please let me know. I thank everyone in advance for your patience and support.
Thanks

Answer 1

Hi AM_Kidd.
Thanks for your reply.
I have done a complete uninstall and re install of iTunes and all related apple programs from my laptop through control panel, add remove programs and also by going through program files and deleting all tracers of any left over folders remove programs may have missed.
My apologies for forgetting to add this in my original post.
Thanks again
