No its not responding to itunes... just black screen.. even my laptop is also not detecting the phone, as it is powered off..
Any other clue?

@ tumababa,

Friend,

I was going through your post, I realized I exactly did what you mentioned in your point 3
3. For those using iphone 4 with gevey/rebel chip inside,DO NOT UPDATE/RESTORE YET,even if u dont av the app called cydia. This is because once u upgrade to ios 5 directly, d chip will not work again (for life) because of d added security on the baseband of ios 5. U just need to wait for a full jailbreak on ios 5 before u upgrade while preserving the baseband that works with the chip (Its tricky but if u are patient, u will bypass d security).

I have an iPhone 4 unlocked with Geavey chip. Also had Cydia app. It had iOS 4.3 Mistakenly I pressed the iOS 5 upgrade while connected to itunes on my laptop.
Now as you explained after baseband upgrade my iPhone is now completely dead.. Not even powering on. Not responding to any connection.

Is there any solution to restore back the old OS?? Or anything else so that I can use it

If possible please let me know & I know you won't repair my iPhone for free
